'''32P20H10V0''' is a [[c/2 orthogonal]] [[spaceship]] with [[period]] {{periodS|20|brief}} found by [[Jason Summers]] on April 8, {{year|2006}}. It is currently the period-20 spaceship with the lowest known population.

This spaceship is a [[puffer 2]] whose output is suppressed by a [[glider]], resulting in the glider being effectively dragged along at a speed of c/2, twice its usual speed.

{{Glossary}}
[[Image:Gosperglidergun.gif|framed|right|The first known gun, the [[Gosper glider gun]]]]
A '''gun''' is a stationary pattern that repeatedly emits [[spaceship]]s (or [[rake]]s) forever. By far the most common type of guns are '''glider guns''', which emit [[glider]]s (the most well-known of which is the [[Gosper glider gun]]); however, guns that emit spaceships of other speeds, including [[c/2 orthogonal]], [[2c/5 orthogonal]], and [[c/12 diagonal]], have also been created.

==History==
The first gun to be discovered, the [[Gosper glider gun]], was found by [[Bill Gosper]] in {{year|1970}}, being the first known pattern in [[Conway's Game of Life]] to exhibit [[infinite growth]]. Since then, many guns have been constructed with various periods and that fire spaceships of various speeds. Due to simple [[glider synthesis|glider syntheses]] of the [[Types_of_spaceships#Standard_spaceship|standard spaceships]] many c/2 spaceship guns are known. The first gun that did not fire gliders or c/2 spaceships was a '''Cordergun''' (a gun that fires [[Cordership]]s) constructed by [[Jason Summers]] in July, {{year|1999}}<ref>{{cite web|url=http://entropymine.com/jason/life/status.html |title=Game of Life Status page |accessdate=October 15, 2010}}</ref> based on a synthesis of a variation of the [[7-engine Cordership]] by [[Stephen Silver]]. In March, {{year|2003}} [[Noam Elkies]] completed the synthesis of [[60P5H2V0]] which [[Dave Greene]] used to construct the [[P416_60P5H2V0_gun|first 2c/5 spaceship gun]] in April of the same year.

In July, {{year|2010}} Dave Greene constructed a few guns for a [[gemini|geminoid]] spaceship.<ref>{{Cite web|url=http://pentadecathlon.com/lifeNews/2010/07/gemini_guns_1.html|title=Gemini guns|author=Adam P. Goucher|date=July 30, 2010|accessdate=October 15, 2010}}</ref> These are the first guns that shoot obliquely-traveling spaceships and at the time were the largest patterns constructed in Life, in terms of their bounding boxes.

On February 17, {{year|2013}} [[Josh Ball]] discovered a simple [[c/7 orthogonal]] spaceship, [[loafer]]. Adam P. Goucher found a synthesis for loafer later that day, allowing the construction of c/7 orthogonal spaceship guns.<ref name="post7466" />

During March {{year|2016}} the [[copperhead]] spaceship was discovered, with a glider synthesis and several guns following suit.<ref name="post28101" />

In {{year|2019}} and {{year|2020}} guns were produced for the spaceships [[46P4H1V0]],<ref name="post84423" /> [[spider]],<ref name="post88186" /> and [[58P5H1V1]],<ref name="post97489" /> of speeds [[c/4 orthogonal]], [[c/5 orthogonal]], and [[c/5 diagonal]] respectively.

==Barrels==
The '''barrel''' of a gun (or rake) is a path along which spaceships travel. The term is most commonly used in the context of the number of barrels a gun or rake possesses, which is the number of distinct spaceship streams emitted by said gun or rake. For example, the [[AK-94]], [[B-52 bomber]] and [[Simkin glider gun]] are said to be '''double-barrelled''' because they produce two streams of gliders. The [[period-256 glider gun]] and [[Gunstar]] and its variants all have four barrels, and [[P94S]] contains a whopping 12 barrels. Given a gun with multiple barrels, one can eliminate barrels by simply placing an [[eater 1]] in the path of the unwanted glider streams.

==Pseudo-period guns==
A '''pseudo-[[period]] gun''' (as opposed to a [[true-period]]gun) is a gun that emits a period n stream of spaceships (or rakes) via a mechanism that oscillates with a period different from n -- this period will necessarily be a multiple of n. Pseudo period n glider guns are known to exist for all periods greater than or equal to 14, with smaller periods being impossible. The first pseudo period 14 gun was built by [[Dietrich Leithner]] in {{year|1995}}.

==True-period guns==
A '''true-period gun''' (as opposed to a [[#Pseudo-period guns|pseudo-period gun]]) is a gun that emits a period n stream of spaceships (or rakes) via a mechanism that oscillates with period equal to n. True period n guns are known to exist for all periods greater than 53<ref>{{Cite web|url=http://www.radicaleye.com/lifepage/patterns/bhept/bhept.html|title=My Experience with B-heptominos in Oscillators|author=Dave Buckingham|accessdate=May 14, 2009|date=October 12, 1996}}</ref>, but only a few smaller periods have been achieved, namely [[Period-20 glider gun|20]], [[True period_22 gun|22]], [[True period 24 gun|24]], [[Gosper glider gun|30]], [[Period-33 glider gun|33]], [[Period-36 glider gun|36]], [[Period-40 glider gun|40]], [[P44 pi-heptomino hassler|44]], [[Period-45 glider gun|45]], [[New gun 1|46]], [[True period 24 gun|48]], [[Period-50 glider gun|50]], [[Period-52 glider gun|52]].

==Guns in Life-like cellular automata==
Due to the existence of some small spaceships in [[Life-like cellular automata]] with birth at two live neighbours (B2), many low-period spaceship guns have been found using tools such as [[WinLifeSearch]]. In contrast, there are very few outer-totalistic rules without B2 (and B0) that are known to contain guns. The following is a list of outer-totalistic rules with neither B0 nor B2 that have known guns:

'''Diamoeba''' is a [[Life-like cellular automaton]] where cells are born if they have 3, 5, 6, 7, or 8 neighbors, and survive if they have 5-8 neighbors. 
Diamoeba is known for its dynamics. Small random soups often dissolve into vacuum or small oscillators while larger soups often generate large oscillating diamonds. 

== Known Objects ==
=== Oscillators ===
There are many oscillators in Diamoeba, although all of the currently known ones are of even period. Below is a collection of the smallest known oscillators (by cell count) from periods 2 until 14.

Saka: /* Generalizing LtL rules to different ranges */ I modified the formula so it is applicable to all neighborhoods, did I do this correctly?

'''Larger than Life''' (abbreviated as '''LTL''' or '''LtL''') is an algorithm that supports a family of [[rule]]s with an extendable [[neighbourhood]], as defined by [[Kellie Michele Evans]] in her 1996 thesis.

==Notation==
Larger than Life rules are supported by [[Golly]] 3.0 and onwards and [[LifeViewer]] build 260 and onwards, using the following notation, created by [[Mirek Wójtowicz]] for [[Mirek's Cellebration|MCell]]:

:<tt>Rr,Cc,Mm,Ssmin..smax,Bbmin..bmax,Nn</tt>

Here:

* <tt>Rr</tt> specifies the range (<tt>r</tt> is from 1 to 500 in Golly and LifeViewer; 1 to 10 in [[Mirek's Cellebration|MCell]]).
* <tt>Cc</tt> specifies the number of states (<tt>c</tt> is from 0 to 255 in Golly, LifeViewer and MCell{{refn|group=note|The documentation for [[Mirek's Cellebration|MCell]] specifies a maximum of 25 states; this is a typo.}})
* <tt>Mm</tt> specifies if the middle cell is included in the neighborhood count (<tt>m</tt> is 0 or 1).
* <tt>Ssmin..smax</tt> specifies the count limits for a state 1 cell to survive.
* <tt>Bbmin..bmax</tt> specifies the count limits for a dead cell to become a birth.
* <tt>Nn</tt> specifies the extended neighborhood type (<tt>n</tt> is <tt>M</tt> for [[Moore neighbourhood|Moore]] or <tt>N</tt> for [[von Neumann neighbourhood|von Neumann]]. Golly and LifeViewer also support <tt>C</tt> for Circular neighborhood. LifeViewer additionally supports <tt>2</tt> for L2, <tt>+</tt> for Cross, <tt>X</tt> for Saltire and <tt>*</tt> for Star neighborhoods).

This diagram shows the extended Moore and von Neumann neighborhoods for range 3:

{| style="margin-left: auto; margin-right: auto;"
|-
| [[File:Moore neighbourhood (range 3).png]]
| [[File:Von Neumann neighbourhood (range 3).png]]
|}

If the number of states (specified after <tt>C</tt>) is greater than 2, then states 1 and above don't die immediately but gradually decay. Note that state values above 1 are not included in the neighborhood counts and thus play no part in deciding the survival of a state 1 cell, nor the birth of an empty cell. <tt>C0</tt> and <tt>C1</tt> are equivalent to <tt>C2</tt>.

==Examples==
The <tt>Patterns/Larger-than-Life</tt> folder included with [[Golly]] contains a number of example patterns (mostly from the [[Mirek's Cellebration|MCell]] collection). The following table shows a number of example rules along with their commonly used names:

Notable patterns which are frequently found within Larger than Life rules include "bugs", which are patterns (usually spaceships, but sometimes oscillators) which are hollow, characterised by those from [[Bosco's Rule]], "solid ships", which are typically extremely slow circular spaceships first noted in 2002 (such as {{LinkCatagolue|xq1846_wgoosqssuuuutvusogz83tvvvvvvvvvvvvvvvvhzwjfvvvvvvvvvvvvvvvvczx17fvvvfff777b731|rule=r10b133t265s154t262|patternname=this one|style=raw}}), and "roomba bugs", travelling patterns that usually stabilise into low-period oscillators after intense amounts of generations but are infrequently found to be real spaceships.

==Alternative rule notations==
Golly and LifeViewer also allow rules to be entered using the notation defined by [[Kellie Evans]] in her thesis. The range, birth limits and survival limits are specified by five integers separated by commas:

:<tt>r,bmin,bmax,smin,smax</tt>

[[Catagolue]], [[apgsearch]] and LifeViewer use a related notation in which the letter <tt>t</tt> ("to") is used to indicate birth/survival condition ranges; the initial <tt>g</tt>''C'' is optional, with the number of states defaulting to two:

:<tt>g</tt>''C''<tt>r</tt>''R''<tt>b</tt>''Bmin''<tt>t</tt>''Bmax''<tt>s</tt>''Smin''<tt>t</tt>''Smax''

These notations assume an extended [[Moore neighbourhood]] in which a live middle cell is included in the neighbourhood count. For example, [[Conway's Game of Life|Life]] can be entered as <tt>1,3,3,3,4</tt> in Evans' notation.

==Generalizing LtL rules to different amounts of neighbors==
Larger than Life rules can be generalized ("converted") to different ranges and even neighborhoods. To convert the range-''r0'' ''n0''-neighborhood rule <tt>Rr0,Cc,Mm,Ssmin0..smax0,Bbmin0..bmax0,Nn0</tt> to a range-''r1'' ''n1''-neighborhood rule:

# Compute ''N'' to equal the ratio of the number of neighbors in a range-''r1'' ''n1''-neighborhood to the number of neighbors in a range-''r0'' ''n0'' neighborhood.
# Multiply the original rule's minimum and maximum birth/survival conditions by ''N'' and round off, to wit:
## Compute ''smin1'' = round(''smin0'' · ''N'').
## Compute ''smax1'' = round(''smax0'' · ''N'').
## Compute ''bmin1'' = round(''bmin0'' · ''N'').
## Compute ''bmax1'' = round(''bmax0'' · ''N'').

The converted rule is <tt>Rr1,Cc,Mm,Ssmin1..smax1,Bbmin1..bmax1,Nn1</tt>.

===Example===
For example, converting the range-2 rule <tt>R2,C0,M1,S5..9,B7..9,NM</tt> to range 7 with the same neighborhood, with the formula for the number of neighbors in a range-''r'' Moore neighborhood being (2 · ''r'' + 1)2, we obtain:

# ''N'' = (2 · 7 + 1)2 / (2 · 2 + 1)2 = 225 / 25 = 9.
# ''smin1'' = 5 · 9 = 45.
# ''smax1'' = 9 · 9 = 81.
# ''bmin1'' = 7 · 9 = 63.
# ''bmax1'' = 9 · 9 = 81.

The converted rule is, therefore, <tt>R7,C0,M1,S45..81,B63..81,NM</tt>.

:''For the range-1 outer-totalistic rule, see [[Bugs (outer-totalistic cellular automaton)]].''

'''Bugs''' (also known as '''Bosco's Rule''') is a [[Larger than Life]] cellular automaton, and perhaps one of the most studied such rules. The rule was devised by [[Kellie Evans]]. The alternative name "Bosco's Rule" is derived from a sparky period 166 oscillator called "Bosco" (see [[OCA:Bugs#Oscillators|Oscillators]]).

== Patterns ==

=== Still lifes ===
The most common still life is the block, similar to [[Block|its Life equivalent]] but as a 6×6 square as opposed to a 2×2.

[[File:bugsblock.png|thumb|center|150px|The 6×6 block. {{LinkCatagolue|code=xs36_vvvvvvz111111|rule=r5b34t45s34t58|style=brief}}]]

Other larger still lifes exist, resembling thick circles.

=== Oscillators ===
Some p2 and p3 oscillators are known in Bugs.

One particularly notable oscillator is a [[Reflectorless rotating oscillator|reflectorless flipping oscillator]] known as ''Bosco'', oscillating at a period of 166. Its period can be increased by passing it near blocks, with the period increasing by 188 for every pair of blocks.

[[File:bosco.png|thumb|center|150px|Bosco {{LinkCatagolue|code=xp166_gsuvvvuuoz7ffvggpc7|rule=r5b34t45s34t58|style=brief}}]]
[[File:bosco2blocks.png|thumb|center|250px|Bosco with two blocks]]

=== Spaceships ===
Multiple spaceships of various speeds are known in Bugs.

=== Infinite growth ===
Multiple bug guns have been constructed using Boscos, with an example shown below.

[[File:buggun.png|frame|center|150px|A gun]]

== Generalization ==
Bugs can be generalised to other ranges, such as the range-10 [[Bugsmovie]], the range-7 "soldier bug" rule containing a p552 [[reflectorless rotating oscillator]], and a range-6 rule containing a quadratic [[replicator]].

Saka: 1 more... again, sorry.

This project is a spin-off from [https://conwaylife.com/forums/viewtopic.php?f=12&t=4488 this forum thread].

This is an attempt to find the smallest stabilisations of the [[still life]] constituent parts found in the [https://catagolue.appspot.com/census/bs123/C1 B/S123 census] on [[Catagolue]]. '''Edits and additions are welcome either on this table or on the thread above!'''

Still lives in [[Conway's Game of Life]] have been excluded from this table. So has the [[dot]] because it is not a still life in B/S123, and also because it is pointlessly trivial.

The metric is by [[population]], then [[bounding box]].

The corresponding project with still life [[island]]s can be found [https://conwaylife.com/w/index.php?title=User:Ian07/Still_life_islands here].

Thank you to muzikbike and gooddogtyson for [[apgsearch]]ing b3s123/C1!

The template to add rows to the table is
<nowiki>|-</nowiki>
<nowiki>| {{LinkCatagolue|CONSTITUENT APGCODE|rule=bs123|style=raw}} || {{LinkCatagolue|STABILISED APGCODE|style=raw}} || YOUR NAME</nowiki>



and please sort by constituent size, then alphanumeric order, thank you
If a still life cannot be stabilised use "none" (without the quotes) as the stabilised apgcode. An example is a 5x5 ring.

Saka: one more...

This project is a spin-off from [https://conwaylife.com/forums/viewtopic.php?f=12&t=4488 this forum thread].

This is an attempt to find the smallest stabilisations of the [[still life]] constituent parts found in the [https://catagolue.appspot.com/census/bs123/C1 B/S123 census] on [[Catagolue]]. '''Edits and additions are welcome either on this table or on the thread above!'''

Still lives in [[Conway's Game of Life]] have been excluded from this table. So has the [[dot]] because it is not a still life in B/S123, and also because it is pointlessly trivial.

The metric is by [[population]], then [[bounding box]].

The corresponding project with still life [[island]]s can be found [https://conwaylife.com/w/index.php?title=User:Ian07/Still_life_islands here].

Thank you to muzikbike and gooddogtyson for [[apgsearch]]ing b3s123/C1!

The template to add rows to the table is
<nowiki>|-</nowiki>
<nowiki>| {{LinkCatagolue|CONSTITUENT APGCODE|rule=bs123|style=raw}} || {{LinkCatagolue|STABILISED APGCODE|style=raw}} || YOUR NAME</nowiki>



and please sort by constituent size, then alphanumeric order, thank you
If a still life cannot be stabilised use "none" (without the quotes) as the stabilised apgcode. An example is a 5x5 ring.

Saka: improvements

This project is a spin-off from [https://conwaylife.com/forums/viewtopic.php?f=12&t=4488 this forum thread].

This is an attempt to find the smallest stabilisations of the [[still life]] constituent parts found in the [https://catagolue.appspot.com/census/bs123/C1 B/S123 census] on [[Catagolue]]. '''Edits and additions are welcome either on this table or on the thread above!'''

Still lives in [[Conway's Game of Life]] have been excluded from this table. So has the [[dot]] because it is not a still life in B/S123, and also because it is pointlessly trivial.

The metric is by [[population]], then [[bounding box]].

The corresponding project with still life [[island]]s can be found [https://conwaylife.com/w/index.php?title=User:Ian07/Still_life_islands here].

Thank you to muzikbike and gooddogtyson for [[apgsearch]]ing b3s123/C1!

The template to add rows to the table is
<nowiki>|-</nowiki>
<nowiki>| {{LinkCatagolue|CONSTITUENT APGCODE|rule=bs123|style=raw}} || {{LinkCatagolue|STABILISED APGCODE|style=raw}} || YOUR NAME</nowiki>



and please sort by constituent size, then alphanumeric order, thank you
If a still life cannot be stabilised use "none" (without the quotes) as the stabilised apgcode. An example is a 5x5 ring.

{| class="wikitable sortable"

This is an attempt to find the smallest stabilisations of the [[still life]] constituent parts found in the [https://catagolue.appspot.com/census/bs123/C1 B/S123 census] on [[Catagolue]]. '''Edits and additions are welcome either on this table or on the thread above!'''

Still lives in [[Conway's Game of Life]] have been excluded from this table. So has the [[dot]] because it is not a still life in B/S123, and also because it is pointlessly trivial.

The metric is by [[population]], then [[bounding box]].

The corresponding project with still life [[island]]s can be found [https://conwaylife.com/w/index.php?title=User:Ian07/Still_life_islands here].

Thank you to muzikbike and gooddogtyson for [[apgsearch]]ing b3s123/C1!

The template to add rows to the table is
<nowiki>|-</nowiki>
<nowiki>| {{LinkCatagolue|CONSTITUENT APGCODE|rule=bs123|style=raw}} || {{LinkCatagolue|STABILISED APGCODE|style=raw}} || YOUR NAME</nowiki>



and please sort by constituent size, then alphanumeric order, thank you
If a still life cannot be stabilised use "none" (without the quotes) as the stabilised apgcode. An example is a 5x5 ring.

# A new variety of Conway's Game of Life dedicated to RIP John Horton Conway's memory.

# In this version, there exist two types of live cells of opposite "sign".
# Two identically behaving "life forms" may coexist and interact with each other.

# The rules of survival and birth are usual, but strictly symmetrical.
# A "negative" cell survives, iff it has 2 or 3 "negative" live neighbours.
# A "negative" cell is born, iff it has 3 "negative" live neighbours.

# Importantly, the number of neighbours is counted as the total sum of their numerical values, which may be 1 or -1.
# Thus, a "positive" cell may be born, if surrounded by 5 "positive" and 2 "negative" neighbours.
# A "negative" cell survives, if surrounded by 5 "negative" and 3 "positive" cells etc.

'''Star Wars''', also known as '''MirekGro''', is a [[Generations]] rule devised by [[Mirek Wójtowicz]] in March 1999. In this rule, a state-0 cell will become state 1 iff it has two state-1 neighbours. A state-1 cell does not change if it has 3, 4 or 5 state-1 neighbours, otherwise it will enter state 2 next tick and then state 3 before dying.

Named after its behaviour that resembles deep space battle scenes, the rule can be described as follows:<ref>{{cite web|url=http://www.mirekw.com/ca/rullex_gene.html#Star%20Wars|title=Cellular Automata rules lexicon|work=Mirek's Cellebration (home page)|author=Mirek Wójtowicz|accessdate=June 22, 2020}}</ref>

{{Cquote|author=[[John Elliott]]|text=StarWars is also an interesting rule from the low-investment standpoint. In particular, it is notable for the abundance, intricacy, and variety of its naturally-occurring glider guns. In general when running "[[soup|au naturel]]" StarWars is active to a degree almost reminiscent of [[OCA:Brian's Brain|Brain]], with the distinction that it likes to build fixed lego-like skeletal structures. In some orbits this latter penchant reaches its zenith, and we get large universe-spanning "shells" possessing an intricate radiate geometry.}}

A collection of patterns in Star Wars rule is in [[Mirek's Cellebration]]. The rule can also run in modern simulators (e.g. [[Golly]] and [[LifeViewer]]) that support Generations rules.

===[[Still life]]s===

Still lives of population 5, 8, 10, 12 and above exists. The only 5-cell still life is the X-[[pentomino]], or '''cross''', which is a common extendable segment in larger still lives.

A group of still lives in the shape of rectangular boxes are invincible from inside, limiting the evolution similar to a [[finite plane]]; for a m×n plane the exterior has a [[bounding box]] of (m+4)×(n+4). An example with m=n=16 is shown above at lower-right corner.

===[[Oscillator]]s===

Due to the two dying states, oscillators of period 2 and 3 are impossible.

Many oscillators consist of one or more lightspeed [[signal]]s, with a leading state-1 cell each, that are running on the surface of the stator. These oscillators are referred to as '''railroads''' because they look like trains running on railways. The mechanism provides at least one specimen for every period p ≥ 4. Specifically, jointing q copies of the X-pentomino orthogonally will give a still life with circumference 6q+6 cells (which has exactly one state-1 cell each in their [[Moore neighbourhood]]s). If 6q+6 = kp for some integer k, then k copies of the signal can be put in the circumference evenly to yield a period-p oscillator. The period-7 example is constructed accordingly.

===[[Spaceship]]s===

The spaceships in Star Wars are all at [[c orthogonal]], thus are also referred to as photons. The structure is extensible to various degrees.

===[[Linear growth]] patterns===

[[Gun]]s (or rather, [[laser]]s) firing the smallest photon exist at all periods above 4, which can be constructed by connecting two still lives to the aforementioned adjustable oscillator.

Usually, abundant guns, [[puffer]]s, [[rake]]s, [[wickstretcher]]s and [[wavestretcher]]s emerge from sufficiently large soups.

===[[Signal]] [[circuit]]s===

Technologies based on the smallest photon have been extensively developed. For instance, shooting the photon at the edge of a still life can split it into two lightspeed signals, which travel on the edge and merge into a photon elsewhere, or are turned into other signals. A small portion of photon conduits is shown above.

Further constructions are possible, for instance an adder.<ref name="post18189" />

===Miscellaneous===

The [[domino]] in this rule expands in a diamond shape, while the [[block]] grows quadratically generating wickstretchers.

'''Bx222''' is a [[composite conduit]], one of the original sixteen [[Herschel conduit]]s, discovered by [[Paul Callahan]] in October {{year|1998}}. It is made up of three [[elementary conduit]]s: [[HF95P]], [[PB68B]] and [[BFx59H]]. After 222 ticks, it produces a backward-traveling inverted [[Herschel]] at (6, -16) relative to the input. In the pattern shown in the infobox, a [[ghost Herschel]] marks the output location.

Its [[recovery time]] is very slow, 271 ticks, because it relies on the output Herschel's [[first natural glider]] to clean up the input Herschel's first natural block (visible in the infobox starting at T=37). Most other conduits include an [[eater1]] to suppress that block, but there's no room for a catalyst in that location in the Bx222.

The conduit produces an extra glider in the northwest, but that glider can only be released if the Herschel is suppressed or if [[staged recovery]] conduits are used, since most elementary H-to-X conduits require an [[eater 1]] to eat the [[first natural glider|first natural block]] of the Herschel. These and/or other early [[catalyst]]s in conduits attached to the Bx222 would be damaged if the NW glider is allowed to escape. Therefore an eater 5 variant is generally required, which prevents the Bx222 from being considered Spartan.

The specific eater 5 variant shown in the infobox allows for an Fx77 and similar conduits to be appended using a simple [[weld]]—a standard [[eater 5]] won't fit as well. F117 and similar conduits can also be appended, but only by replacing the eater 5 variant with a [[7x9 eater]] or something similar, and using a more complicated weld.

***Custom search patterns
**WLS
**Add some stuff to the "Finding good rules" tutorial
***Some details for OT and INT
***LTL?
*Make some articles for LTL rules (Maybe).
**Mainly <s>Bugs / Bosco's Rule</s> (Wait, someone made it already?), maybe even Soldier Bugs?
Not on the wiki, but still related to cellular automata:
*Finish Diamoeba taxonomy thing
*Continue those dang LSSS searches

==CiteDiscord template?==

Was thinking about this since [[User:Dvgrn]] added a Discord citation to the [[Max]] article. Would there be any objections to a template to cite the [https://discord.gg/BCuYCEn Conwaylife Lounge Discord server]? It is a public server, after all, and there have been quite a few notable discoveries and developments announced there over the years. [[User:Ian07|Ian07]] ([[User talk:Ian07|talk]]) 17:53, 16 February 2020 (UTC)
: Sounds good to me. I'd also like a Templates Cheat Sheet page under [[LifeWiki:Editor_pages|How to Contribute]] somewhere, probably just a section in [[Help:Templates]]. There are examples there of how to use some templates, but for many of them I currently just go hunting around randomly in articles until I find a good example of how it's used, and then copy and modify that. As the number of templates increases, this is starting to seem more and more, um, suboptimal. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 15:06, 17 February 2020 (UTC)

==Black ribbon==
Briefly popping out of the woodwork to mourn [[Richard K. Guy|Rich]] --- I had the idea of adding a black ribbon in the lower right corner of pages. This is added by a bit of code in <tt>[[MediaWiki:Common.js]]</tt>, with some supporting CSS in <tt>[[MediaWiki:Common.css]]</tt>. To turn this off again, simply comment out the line that says

$( document ).ready(function() {
console.log( "ready!" );
addMourningRibbon();
});

near the bottom of <tt>[[MediaWiki:Common.js]]</tt>. (Actually, commenting out the call to <tt>addMourningRibbon</tt> there will be enough.) Leave the rest of the code and the CSS in though; that way the ribbon can be reused next time there is a death in the community. (The link on the ribbon is set a little further up, and can easily be adjusted as needed.)

<s>N.B. --- the ribbon itself is a bit fiddly and doesn't always appear; I suspect this has to do with page caching, but I know too little about Javascript, Mediawiki and all that jazz to get to the bottom of it. Perhaps someone else who knows more can help.</s> Using jQuery (which, thankfully, is included in MediaWiki) fixed this, so we should now have a ribbon on all pages, always. [[User:Apple Bottom|Apple Bottom]] ([[User talk:Apple Bottom|talk]]) 10:13, 11 March 2020 (UTC)

: The black ribbon has been there for over ten days now; anyone want to suggest an appropriate total time period for it? I wandered over to <tt>[[MediaWiki:Common.js]]</tt> to see what would have to be done to turn it off, but found that I didn't have permission:
Permissions for editing of sitewide CSS/JS/JSON files were recently separated from the editinterface right.
If you do not understand why you are getting this error, see [https://www.mediawiki.org/wiki/MediaWiki_1.32/interface-admin mw:MediaWiki_1.32/interface-admin].
:Luckily I had permission to give myself permission, so I can now comment out the relevant line. The Internet suggests there are common 7-day and 30-day traditional mourning periods. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 21:32, 22 March 2020 (UTC)

::10 days seems fine to me. And yes, I had the same issue with permissions. Bit weird that MediaWiki doesn't give the relevant right to admins by default, but perhaps this is so that admins who're not aware of what they're doing won't accidentally break things.

== LifeViewer and RLE on OCA subpages ==

I was just looking at some experimental pages that [https://conwaylife.com/wiki/User:Ultimium Hunting/Ultimium] has put together for LeapLife. For example, the small knightship in LeapLife is called a "lepa", so it's presumably going to go under [[OCA:LeapLife/Lepa]].

But that brings up all kinds of questions. Look at [https://conwaylife.com/wiki/User:Ultimium/LeapWiki/Lepa Hunting's experimental Lepa page]. If RLE is added in the RLE: namespace for a lepa, and for all the other things Hunting will want to document, then those patterns will end up in the main pattern collection, right? That doesn't seem like such a good idea. It would be nice to be able to put RLE someplace where LifeViewer can still find it, but it doesn't end up in the main LifeWiki pattern collection. We only have a few non-Life patterns so far, like [[Bomber]], but it seems as if things could get out of control pretty fast if people want to add LifeViewer support for OCA pattern articles.

It seems like some different templates might be needed, to point to the alternate RLE namespace (if that gets created), and to get rid of irrelevant stuff like the links to Catagolue syntheses which won't exist for OCA patterns.

Thoughts on this? Would it be better to skip the templates, and just recommend that OCA patterns should keep their RLEs directly in the articles, as part of embedded LifeViewer text? Then I think the "RLE: here Plaintext: here" template won't work too well, and an alternate embedded-LifeViewer template for OCA patterns might be a good idea. (?) [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 16:09, 7 April 2020 (UTC)

: I think there should be a separate category, say OCARLE: and an option in the template |rle = oca for checking specifically under that header. Either that or one of the three other options:
:*Removing the pattern collection.
:*Creating a new wiki for other cellular automata.
:*Excluding all OCA RLE pages from the collection.

:: I agree with OCARLE. [[User:Ultimium|Ultimium]] ([[User talk:Ultimium|talk]]) 03:15, 30 May 2020 (UTC)

:Giving a quick search for RLE:bg gives 5 RLE pages as well, all in LeapLife. I think those should be excluded even if the others can't be, especially if I'm going to create more. (and Hunting's too, afaik there's only RLE:Lepa and RLE:Crawfish so that shouldn't be too hard) [[User:Bubblegum|Bubblegum]] ([[User talk:Bubblegum|talk]]) 18:25, 29 May 2020 (UTC)

: I don't object to either of these ideas, just want to point out that the latter option actually won't require the creation of a new template - if ''rle'' is specified instead of ''pname'', the links won't appear. [[User:Ian07|Ian07]] ([[User talk:Ian07|talk]]) 21:24, 7 April 2020 (UTC)

:: I prefer to use a seperate collection instead of the RLE embedded in the page, and a template for OCA patterns, for, um, for no reason. I mean they will be easier to access and manage. [[User:Ultimium|Ultimium]] ([[User talk:Ultimium|talk]]) 06:11, 8 April 2020 (UTC)

::: So far, the only good way to add patterns to OCA pages is what Hunting/Ultimium has done, e.g., with [[User:Ultimium/LeapWiki/Crawfish]]. But this currently means that the crawfish RLE is going to get added to the omnibus RLE collection downloadable from the main page. There are currently 66 OCA patterns scattered in among the 2300+ Life patterns. Might it be a good idea to split out all OCA patterns and provide a separate downloadable collection?
[[RLE
:::: I'm just mimicking Apple Bottom's [[User:Apple Bottom/Day & Night|Day & Night Wiki]]. I agree, we should split out all OCA patterns. {{unsigned|Ultimium}}

::: Also it might be worth adjusting the template used there somehow, to clearly label the crawfish spaceship in the infobox as being in a non-B3/S23 rule. (?) [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 13:49, 19 April 2020 (UTC)

:::: I like the current idea of adding a new OCA RLE category so they won't get lumped into the B3/S23 stuff. Yes, I think adjusting the infobox template to make it more visible that the pattern is not a CGoL pattern is worth doing. Also, there are some RLEs I'm using in some of my user pages for OCA patterns. They are [[RLE:Smosmos]], [[RLE:Sakaphipush]], [[RLE:Sakacapush]], [[RLE:Sakaw2]], and [[RLE:Sakasaladc8]] if I didn't miss any. [[User:Saka|Saka]] ([[User talk:Saka|talk]]) 13:42, 30 May 2020 (UTC)

== "Non-Lifelike" CAs -- cleanup suggested ==

[https://www.conwaylife.com/forums/viewtopic.php?p=93581#p93581 This post by BokaBB] got me looking at the rule pages that have been collected in the OCA namespace. [https://www.conwaylife.com/w/index.php?title=Category:Life-like_cellular_automata Category:Life-like cellular automata] includes several isotropic non-totalistic rules ([[OCA:GlideLife]], [[OCA:Goat Flock]], [[OCA:Just Friends]], [[OCA:Salad]], [[OCA:Snowflakes]], [[OCA:Tlife]], and [[OCA:Wlife]], so far, and I might have missed something.) There seems to be standard wording in all of these saying " ''{Rule R} is a non-totalistic Life-like cellular automaton". But this just plain isn't right: a non-totalistic CA can't be Life-like.

The standard wording links to [[Non-totalistic Life-like cellular automaton]], which shouldn't really exist because technically there is no such thing. I guess the right name for that article should probably be just [[Non-totalistic cellular automaton]], and "Life-like" should also be removed from [[Isotropic non-totalistic Life-like cellular automaton]] and [[Non-isotropic_Life-like_cellular_automaton]] (both the titles and the article text).

Does anyone have any objection if I do a bunch of editing to fix this, before the problem gets any worse? Or does someone really want to LifeWiki-officially redefine what "Life-like" means? The current definition is so widely accepted that it's even [https://en.wikipedia.org/wiki/Life-like_cellular_automaton on Wikipedia]: "Life-like" implies an outer-totalistic rule, so it's '''much''' more limited than the space of isotropic non-totalistic rules.

I'd like to add a couple of new LifeWiki categories (or have someone competent do it for me): one for "Other Cellular Automata" in general (Life-like '''and''' isotropic NT rules), and one for isotropic NT rules specifically. At the moment it seems kind of hard to find a category page for all OCA: namespace articles -- you can't just search for "OCA" or "OCA:" (right?)

If we want to be really brave, we could make the isotropic NT category something like "Iso-NT". If that caught on -- big "if" -- then there would finally be a short standard way to say "isotropic non-totalistic". Maybe someday people could just say "isont" or "anisont" and expect to be understood. ("Aniso-NT" would be the equivalent category for "anisotropic non-totalistic", but there doesn't seem to be any point in creating that category since nobody's come up with a rule worth naming in that rulespace yet.)

... If anyone '''does''' have an objection, please suggest something we could do instead! [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 16:40, 7 April 2020 (UTC)

: This is probably a bit late, but I think those bunch of edits are a good idea (Which it appears you have not done yet). And yes, I do agree with defining "Life-like" as strictly for Outer-totalistic rules. Nope, you can't just search "OCA" or "OCA:", so yeah, it's currently impossible to find a category with all the OCA rules and nothing more: The "Life-like_cellular_automata" category doesn't include LTL and multistate rules, while the "Cellular_automata" category also lists a bunch of non-rule pages such as the general articles for rulespaces and the lists of rules investigated on Catagolue (which, aren't they obsolete?).

: Back on the definition of "Life-like", the inclusion of IsNT (Isotropic Non Totalistic) rules in the category of Life-like CA on the wiki will probably make new CA-Enthusiasts think that they are included in Life-like CA, which might have an effect on the forum.

:Also, over on the Discord the standard way to write "Isotropic Non-Totalistic" quicker seems to be "INT", and Heavpoot suggested (somewhat jokingly?) "AINT" for "AnIsotropic Non-Totalistic" (Perhaps "AiNT" is better), or we could just refer to them as "MAP Rules", although yeah, that isn't very good, as MAP includes Isotropic and totalistic rules as well. [[User:Saka|Saka]] ([[User talk:Saka|talk]]) 14:04, 30 May 2020 (UTC)

== Expanding Covered OCA Rules ==

Does anyone think that having articles for rules beyond Life-Like and Isotropic Non-totalistic should be on here, like Wireworld or Langton's Ant? These would still go under the OCA namespace, obviously. If anyone has any thoughts on this, that would be great. [[User:AforAmpere|AforAmpere]] ([[User talk:AforAmpere|talk]]) 5:02, 16 April 2020 (UTC)
: As far as I'm concerned, articles for any reasonably well-known rule would be very welcome in the OCA namespace. Wireworld and Langton's Ant definitely count as good examples.

: A big reason for inventing the OCA namespace was to provide a place for this kind of information, without accidentally cluttering up the "Life" part of the LifeWiki. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 14:08, 19 April 2020 (UTC)

: I would like to contribute to these pages. [[User:Ultimium|Ultimium]] ([[User talk:Ultimium|talk]]) 02:00, 20 April 2020 (UTC)

Mmm, a similar discussion took place three years ago, see [[LifeWiki:Tiki bar/Archive/2017#Lists_of_rules]]. Speaking of articles for other cellular automata, how about those red links in the [[list of Generations rules]]? There are a variety of rules, and therefore it will be a huge amount of work if we want to write a page for each. Or should we consider their historical/current significance first? Need Generations experts here. (I dislike red links...Wait, I shouldn't show personal feelings here.) [[User:GUYTU6J|GUYTU6J]] ([[User talk:GUYTU6J|talk]]) 16:50, 13 May 2020 (UTC)

:: Personal feelings? Nah, that's just on the actual article pages. I really like red links, because they encourage other people to do documentation work... It would make sense to me to add a page for each of the major Generations rules in the [http://psoup.math.wisc.edu/mcell/download.html old MCell 4.20 collection], just for starters. There's usually some descriptive text that could be lifted out of Mirek's representative {RULENAME}.mcl file, as a starting point.

:: The named Generations rules in the MCell pattern collection are Banners, Bombers, Brain 6, Brian's Brain, Burst, BurstII, Caterpillars, Chenille, Ebb&Flow, Ebb&FlowII, Faders, Fireworks, Frogs, Glisserati, Nova, Rake, SediMental, Snake, Spirals, StarWars, Sticks, Swirl, Transers, TransersII, Wanderers, and Worms. There's also an "Other Rules" folder, but it has just a couple of patterns in it -- one in the Star Wars family, and an unnamed explosive one (345/24/25) with a side-effect production of some Rule-90-ish behavior. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 15:08, 30 May 2020 (UTC)

== Criteria for notable INT rules ==

The discussion at [[LifeWiki:Tiki bar/Archive/2019#Non-notable isotropic rules]] inspired me to move OCA:Wlife to User:Evin/Wlife. Previously the reason for proposed deletion was "non-notable rule; forum thread only has 9 posts in total". Sounds reasonable, right?

But then here come the questions. Can we develop some universal criteria for a section in [[LifeWiki:Notability]] about an INT rule? Which rule warrants an article on OCA namespace, and which rule is at most qualified for a User subpage? Rules differ greatly in behaviour and potential for interesting technology, but still I think "Well-explored syntheses", "Turing-complete", "Orthogonoid/Demonoid engineered explicitly", or something along these lines, may suffice for the judgement.

Related, should we encourage users to write about their custom INT rule ''in their User subpage first'', and move it to the official OCA namespace after reaching a consensus that it is well-developed and notable enough according to some guideline? [[User:GUYTU6J|GUYTU6J]] ([[User talk:GUYTU6J|talk]]) 02:52, 3 June 2020 (UTC)

: I don't think that a rule has to be Turing-complete and have a Orthogonoid/demonoid to be interesting / to warrant their own wiki page, but that's just my opinion. Making a universal definition for interesting INT rules will be hard, as is making a strict definition of interesting anything. But if we do make one, maybe we could judge the rule by it's activity as well? Number of active explorers, number of (useful / constructive) posts in the rule's thread (that are related to the rule, not off-topic chatting), that kind of stuff. One problem I can see with that approach, however, is that some genuinely interesting rules do get unnoticed, but maybe that's outside the scope of this... discussion?

:On the last part, yeah, I think that's a good idea. Related to that, is the wiki O.K.a.y. with a bunch of pages under the userspace? We already have a good amount, and if we encourage that we'll have some more. Also, maybe encourage users to write a page under their username if they think their rule is interesting enough (Maybe that will slightly decrease the number of user subpages?).

:I don't think we should have strict guidelines but rather a board / panel of people that will decide if a rule warrants a wiki page.

:EDIT: I forgot, I do think that the current Wlife page is a bit too empty to be in the official™ OCA namespace. [[User:Saka|Saka]] ([[User talk:Saka|talk]]) 04:55, 3 June 2020 (UTC)

Wikipedia has the [https://en.wikipedia.org/wiki/Wikipedia:Village_pump Village pump], Wiktionary has the [https://en.wiktionary.org/wiki/Wiktionary:Beer_parlour Beer parlour], but the LifeWiki's lacked a central page for discussion so far other than [[User talk:Nathaniel]].

==CiteDiscord template?==

Was thinking about this since [[User:Dvgrn]] added a Discord citation to the [[Max]] article. Would there be any objections to a template to cite the [https://discord.gg/BCuYCEn Conwaylife Lounge Discord server]? It is a public server, after all, and there have been quite a few notable discoveries and developments announced there over the years. [[User:Ian07|Ian07]] ([[User talk:Ian07|talk]]) 17:53, 16 February 2020 (UTC)
: Sounds good to me. I'd also like a Templates Cheat Sheet page under [[LifeWiki:Editor_pages|How to Contribute]] somewhere, probably just a section in [[Help:Templates]]. There are examples there of how to use some templates, but for many of them I currently just go hunting around randomly in articles until I find a good example of how it's used, and then copy and modify that. As the number of templates increases, this is starting to seem more and more, um, suboptimal. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 15:06, 17 February 2020 (UTC)

==Black ribbon==
Briefly popping out of the woodwork to mourn [[Richard K. Guy|Rich]] --- I had the idea of adding a black ribbon in the lower right corner of pages. This is added by a bit of code in <tt>[[MediaWiki:Common.js]]</tt>, with some supporting CSS in <tt>[[MediaWiki:Common.css]]</tt>. To turn this off again, simply comment out the line that says

$( document ).ready(function() {
console.log( "ready!" );
addMourningRibbon();
});

near the bottom of <tt>[[MediaWiki:Common.js]]</tt>. (Actually, commenting out the call to <tt>addMourningRibbon</tt> there will be enough.) Leave the rest of the code and the CSS in though; that way the ribbon can be reused next time there is a death in the community. (The link on the ribbon is set a little further up, and can easily be adjusted as needed.)

<s>N.B. --- the ribbon itself is a bit fiddly and doesn't always appear; I suspect this has to do with page caching, but I know too little about Javascript, Mediawiki and all that jazz to get to the bottom of it. Perhaps someone else who knows more can help.</s> Using jQuery (which, thankfully, is included in MediaWiki) fixed this, so we should now have a ribbon on all pages, always. [[User:Apple Bottom|Apple Bottom]] ([[User talk:Apple Bottom|talk]]) 10:13, 11 March 2020 (UTC)

: The black ribbon has been there for over ten days now; anyone want to suggest an appropriate total time period for it? I wandered over to <tt>[[MediaWiki:Common.js]]</tt> to see what would have to be done to turn it off, but found that I didn't have permission:
Permissions for editing of sitewide CSS/JS/JSON files were recently separated from the editinterface right.
If you do not understand why you are getting this error, see [https://www.mediawiki.org/wiki/MediaWiki_1.32/interface-admin mw:MediaWiki_1.32/interface-admin].
:Luckily I had permission to give myself permission, so I can now comment out the relevant line. The Internet suggests there are common 7-day and 30-day traditional mourning periods. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 21:32, 22 March 2020 (UTC)

::10 days seems fine to me. And yes, I had the same issue with permissions. Bit weird that MediaWiki doesn't give the relevant right to admins by default, but perhaps this is so that admins who're not aware of what they're doing won't accidentally break things.

== LifeViewer and RLE on OCA subpages ==

I was just looking at some experimental pages that [https://conwaylife.com/wiki/User:Ultimium Hunting/Ultimium] has put together for LeapLife. For example, the small knightship in LeapLife is called a "lepa", so it's presumably going to go under [[OCA:LeapLife/Lepa]].

But that brings up all kinds of questions. Look at [https://conwaylife.com/wiki/User:Ultimium/LeapWiki/Lepa Hunting's experimental Lepa page]. If RLE is added in the RLE: namespace for a lepa, and for all the other things Hunting will want to document, then those patterns will end up in the main pattern collection, right? That doesn't seem like such a good idea. It would be nice to be able to put RLE someplace where LifeViewer can still find it, but it doesn't end up in the main LifeWiki pattern collection. We only have a few non-Life patterns so far, like [[Bomber]], but it seems as if things could get out of control pretty fast if people want to add LifeViewer support for OCA pattern articles.

It seems like some different templates might be needed, to point to the alternate RLE namespace (if that gets created), and to get rid of irrelevant stuff like the links to Catagolue syntheses which won't exist for OCA patterns.

Thoughts on this? Would it be better to skip the templates, and just recommend that OCA patterns should keep their RLEs directly in the articles, as part of embedded LifeViewer text? Then I think the "RLE: here Plaintext: here" template won't work too well, and an alternate embedded-LifeViewer template for OCA patterns might be a good idea. (?) [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 16:09, 7 April 2020 (UTC)

: I think there should be a separate category, say OCARLE: and an option in the template |rle = oca for checking specifically under that header. Either that or one of the three other options:
:*Removing the pattern collection.
:*Creating a new wiki for other cellular automata.
:*Excluding all OCA RLE pages from the collection.

:: I agree with OCARLE. [[User:Ultimium|Ultimium]] ([[User talk:Ultimium|talk]]) 03:15, 30 May 2020 (UTC)

:Giving a quick search for RLE:bg gives 5 RLE pages as well, all in LeapLife. I think those should be excluded even if the others can't be, especially if I'm going to create more. (and Hunting's too, afaik there's only RLE:Lepa and RLE:Crawfish so that shouldn't be too hard) [[User:Bubblegum|Bubblegum]] ([[User talk:Bubblegum|talk]]) 18:25, 29 May 2020 (UTC)

: I don't object to either of these ideas, just want to point out that the latter option actually won't require the creation of a new template - if ''rle'' is specified instead of ''pname'', the links won't appear. [[User:Ian07|Ian07]] ([[User talk:Ian07|talk]]) 21:24, 7 April 2020 (UTC)

:: I prefer to use a seperate collection instead of the RLE embedded in the page, and a template for OCA patterns, for, um, for no reason. I mean they will be easier to access and manage. [[User:Ultimium|Ultimium]] ([[User talk:Ultimium|talk]]) 06:11, 8 April 2020 (UTC)

::: So far, the only good way to add patterns to OCA pages is what Hunting/Ultimium has done, e.g., with [[User:Ultimium/LeapWiki/Crawfish]]. But this currently means that the crawfish RLE is going to get added to the omnibus RLE collection downloadable from the main page. There are currently 66 OCA patterns scattered in among the 2300+ Life patterns. Might it be a good idea to split out all OCA patterns and provide a separate downloadable collection?
[[RLE
:::: I'm just mimicking Apple Bottom's [[User:Apple Bottom/Day & Night|Day & Night Wiki]]. I agree, we should split out all OCA patterns. {{unsigned|Ultimium}}

::: Also it might be worth adjusting the template used there somehow, to clearly label the crawfish spaceship in the infobox as being in a non-B3/S23 rule. (?) [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 13:49, 19 April 2020 (UTC)

:::: I like the current idea of adding a new OCA RLE category so they won't get lumped into the B3/S23 stuff. Yes, I think adjusting the infobox template to make it more visible that the pattern is not a CGoL pattern is worth doing. Also, there are some RLEs I'm using in some of my user pages for OCA patterns. They are [[RLE:Smosmos]], [[RLE:Sakaphipush]], [[RLE:Sakacapush]], [[RLE:Sakaw2]], and [[RLE:Sakasaladc8]] if I didn't miss any. [[User:Saka|Saka]] ([[User talk:Saka|talk]]) 13:42, 30 May 2020 (UTC)

== "Non-Lifelike" CAs -- cleanup suggested ==

[https://www.conwaylife.com/forums/viewtopic.php?p=93581#p93581 This post by BokaBB] got me looking at the rule pages that have been collected in the OCA namespace. [https://www.conwaylife.com/w/index.php?title=Category:Life-like_cellular_automata Category:Life-like cellular automata] includes several isotropic non-totalistic rules ([[OCA:GlideLife]], [[OCA:Goat Flock]], [[OCA:Just Friends]], [[OCA:Salad]], [[OCA:Snowflakes]], [[OCA:Tlife]], and [[OCA:Wlife]], so far, and I might have missed something.) There seems to be standard wording in all of these saying " ''{Rule R} is a non-totalistic Life-like cellular automaton". But this just plain isn't right: a non-totalistic CA can't be Life-like.

The standard wording links to [[Non-totalistic Life-like cellular automaton]], which shouldn't really exist because technically there is no such thing. I guess the right name for that article should probably be just [[Non-totalistic cellular automaton]], and "Life-like" should also be removed from [[Isotropic non-totalistic Life-like cellular automaton]] and [[Non-isotropic_Life-like_cellular_automaton]] (both the titles and the article text).

Does anyone have any objection if I do a bunch of editing to fix this, before the problem gets any worse? Or does someone really want to LifeWiki-officially redefine what "Life-like" means? The current definition is so widely accepted that it's even [https://en.wikipedia.org/wiki/Life-like_cellular_automaton on Wikipedia]: "Life-like" implies an outer-totalistic rule, so it's '''much''' more limited than the space of isotropic non-totalistic rules.

I'd like to add a couple of new LifeWiki categories (or have someone competent do it for me): one for "Other Cellular Automata" in general (Life-like '''and''' isotropic NT rules), and one for isotropic NT rules specifically. At the moment it seems kind of hard to find a category page for all OCA: namespace articles -- you can't just search for "OCA" or "OCA:" (right?)

If we want to be really brave, we could make the isotropic NT category something like "Iso-NT". If that caught on -- big "if" -- then there would finally be a short standard way to say "isotropic non-totalistic". Maybe someday people could just say "isont" or "anisont" and expect to be understood. ("Aniso-NT" would be the equivalent category for "anisotropic non-totalistic", but there doesn't seem to be any point in creating that category since nobody's come up with a rule worth naming in that rulespace yet.)

... If anyone '''does''' have an objection, please suggest something we could do instead! [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 16:40, 7 April 2020 (UTC)

: This is probably a bit late, but I think those bunch of edits are a good idea (Which it appears you have not done yet). And yes, I do agree with defining "Life-like" as strictly for Outer-totalistic rules. Nope, you can't just search "OCA" or "OCA:", so yeah, it's currently impossible to find a category with all the OCA rules and nothing more: The "Life-like_cellular_automata" category doesn't include LTL and multistate rules, while the "Cellular_automata" category also lists a bunch of non-rule pages such as the general articles for rulespaces and the lists of rules investigated on Catagolue (which, aren't they obsolete?).

: Back on the definition of "Life-like", the inclusion of IsNT (Isotropic Non Totalistic) rules in the category of Life-like CA on the wiki will probably make new CA-Enthusiasts think that they are included in Life-like CA, which might have an effect on the forum.

:Also, over on the Discord the standard way to write "Isotropic Non-Totalistic" quicker seems to be "INT", and Heavpoot suggested (somewhat jokingly?) "AINT" for "AnIsotropic Non-Totalistic" (Perhaps "AiNT" is better), or we could just refer to them as "MAP Rules", although yeah, that isn't very good, as MAP includes Isotropic and totalistic rules as well.

== Expanding Covered OCA Rules ==

Does anyone think that having articles for rules beyond Life-Like and Isotropic Non-totalistic should be on here, like Wireworld or Langton's Ant? These would still go under the OCA namespace, obviously. If anyone has any thoughts on this, that would be great. [[User:AforAmpere|AforAmpere]] ([[User talk:AforAmpere|talk]]) 5:02, 16 April 2020 (UTC)
: As far as I'm concerned, articles for any reasonably well-known rule would be very welcome in the OCA namespace. Wireworld and Langton's Ant definitely count as good examples.

: A big reason for inventing the OCA namespace was to provide a place for this kind of information, without accidentally cluttering up the "Life" part of the LifeWiki. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 14:08, 19 April 2020 (UTC)

: I would like to contribute to these pages. [[User:Ultimium|Ultimium]] ([[User talk:Ultimium|talk]]) 02:00, 20 April 2020 (UTC)

Mmm, a similar discussion took place three years ago, see [[LifeWiki:Tiki bar/Archive/2017#Lists_of_rules]]. Speaking of articles for other cellular automata, how about those red links in the [[list of Generations rules]]? There are a variety of rules, and therefore it will be a huge amount of work if we want to write a page for each. Or should we consider their historical/current significance first? Need Generations experts here. (I dislike red links...Wait, I shouldn't show personal feelings here.) [[User:GUYTU6J|GUYTU6J]] ([[User talk:GUYTU6J|talk]]) 16:50, 13 May 2020 (UTC)

:: Personal feelings? Nah, that's just on the actual article pages. I really like red links, because they encourage other people to do documentation work... It would make sense to me to add a page for each of the major Generations rules in the [http://psoup.math.wisc.edu/mcell/download.html old MCell 4.20 collection], just for starters. There's usually some descriptive text that could be lifted out of Mirek's representative {RULENAME}.mcl file, as a starting point.

:: The named Generations rules in the MCell pattern collection are Banners, Bombers, Brain 6, Brian's Brain, Burst, BurstII, Caterpillars, Chenille, Ebb&Flow, Ebb&FlowII, Faders, Fireworks, Frogs, Glisserati, Nova, Rake, SediMental, Snake, Spirals, StarWars, Sticks, Swirl, Transers, TransersII, Wanderers, and Worms. There's also an "Other Rules" folder, but it has just a couple of patterns in it -- one in the Star Wars family, and an unnamed explosive one (345/24/25) with a side-effect production of some Rule-90-ish behavior. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 15:08, 30 May 2020 (UTC)

== Criteria for notable INT rules ==

The discussion at [[LifeWiki:Tiki bar/Archive/2019#Non-notable isotropic rules]] inspired me to move OCA:Wlife to User:Evin/Wlife. Previously the reason for proposed deletion was "non-notable rule; forum thread only has 9 posts in total". Sounds reasonable, right?

But then here come the questions. Can we develop some universal criteria for a section in [[LifeWiki:Notability]] about an INT rule? Which rule warrants an article on OCA namespace, and which rule is at most qualified for a User subpage? Rules differ greatly in behaviour and potential for interesting technology, but still I think "Well-explored syntheses", "Turing-complete", "Orthogonoid/Demonoid engineered explicitly", or something along these lines, may suffice for the judgement.

Related, should we encourage users to write about their custom INT rule ''in their User subpage first'', and move it to the official OCA namespace after reaching a consensus that it is well-developed and notable enough according to some guideline? [[User:GUYTU6J|GUYTU6J]] ([[User talk:GUYTU6J|talk]]) 02:52, 3 June 2020 (UTC)

: I don't think that a rule has to be Turing-complete and have a Orthogonoid/demonoid to be interesting / to warrant their own wiki page, but that's just my opinion. Making a universal definition for interesting INT rules will be hard, as is making a strict definition of interesting anything. But if we do make one, maybe we could judge the rule by it's activity as well? Number of active explorers, number of (useful / constructive) posts in the rule's thread (that are related to the rule, not off-topic chatting), that kind of stuff. One problem I can see with that approach, however, is that some genuinely interesting rules do get unnoticed, but maybe that's outside the scope of this... discussion?

:On the last part, yeah, I think that's a good idea. Related to that, is the wiki O.K.a.y. with a bunch of pages under the userspace? We already have a good amount, and if we encourage that we'll have some more. Also, maybe encourage users to write a page under their username if they think their rule is interesting enough (Maybe that will slightly decrease the number of user subpages?).

:I don't think we should have strict guidelines but rather a board / panel of people that will decide if a rule warrants a wiki page.[[User:Saka|Saka]] ([[User talk:Saka|talk]]) 04:53, 3 June 2020 (UTC)

The census is primarily focused on asymmetric soups in [[Conway's Game of Life|Conway's Life]], but supports arbitrary [[Life-like cellular automaton|outer-totalistic]] and [[Non-totalistic Life-like cellular automaton|non-totalistic]] rules and a variety of [[symmetry|symmetries]].{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/census/<rule>/<symmetry></nowiki></tt>}} Over 100 users have contributed to the census.

The results are obtained by evolving random [[soup]]s of size 16×16 with [[density]] 0.5 in an infinite planar [[universe]]; as of {{:Catagolue/Stats|date}}, at least {{:Catagolue/Stats|numsoups}} soups have been investigated by the census's participants, yielding a total of at least {{:Catagolue/Stats|numobjects}} objects of {{:Catagolue/Stats|distinctobjects}} distinct types. Submissions of new results (called "hauls") are subjected to both statistical tests and peer-review by other participants before being committed to the census.

Catagolue is primarily fed by [[apgsearch]] 4.x and 5.x (apgluxe). Each resulting object is identified by [[apgsearch]] by its unique [[apgcode]]; the Catagolue website gives overviews over the various classes of objects found, and provides further information as well as sample soups for each object.{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/object/<apgcode>/<rule></nowiki></tt>}} A simple text-based interface for querying sample soups, including their owners, also exists.{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/attribute/<apgcode>/<rule>/<symmetry></nowiki></tt>}}

==Other rules==
{{Main|List of rules investigated on Catagolue}}
Catagolue also collects census data on various rules other than Conway's Game of Life. In practice, only non-exploding rules can reasonably be investigated unless a certain symmetry can be assured to never explode.

As of January 15, 2019, Catagolue officially supports the following types of cellular automata:
*Arbitrary [[Life-like cellular automaton|outer-totalistic]] rules.
*[[Isotropic non-totalistic Life-like cellular automaton|Isotropic non-totalistic]] rules. (in [[Hensel notation]])
*[[Isotropic]] [[von Neumann neighbourhood]] rules. (implicitly by isotropic non-totalistic [[Moore neighbourhood]] rules)
*Higher-range outer totalistic (HROT) rules. (up to range 5)
*[[Larger than Life]] rules. (up to range 7)
*Totalistic and isotropic [[hexagonal neighbourhood]] rules.
*[[Generations]] variants of all rules listed above.
*[[Life-like cellular automaton|Outer-totalistic]] [[rulespace|B0 rules]] with two states.
*[[BSFKL]] rules.
*[[Deficient]] rules.
*[[Extended Generations]] rules.
*Custom [[Golly]] ruletables.

{{:Catagolue/Stats|numrules}} rules have been investigated at as of {{:Catagolue/Stats|date}}, including the following close Life variants:

* B3/S238 ([[EightLife]])
* B36/S23 ([[HighLife]])
* B368/S238 ([[LowDeath]])
* B38/S23 ([[Pedestrian Life]])
* B38/S238 ([[HoneyLife]])
* B3/S2-i34q ([[tlife]])
* B36/S2-i34q ([[thighlife]])
* B37/S2-i34q ([[tdrylife]])
* B38/S2-i34q ([[tpedestrianlife]])

Other notable rules investigated include:

* B3/S12 ([[Flock]])
* B3/S13 ([[LowLife]])
* B345/S5 ([[Long Life]])
* B36/S125 ([[2x2]])
* B3678/S34678 ([[Day & Night]])
* B368/S245 ([[Move]], aka [[Morley]])
* B2-a/S12 ([[Just Friends]])
* B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e ([[Snowflakes]])
* R5,C0,M1,S34..58,B34..45,NM ([[Bugs]])

A cached list of all rule-symmetry combinations investigated, sorted by last update, is also available.<ref name="post95134" />{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/abclist</nowiki></tt>}}

==Haul verification==
Hauls for official censuses of [[Life-like cellular automaton|Life-like]] rules with at least one trillion objects are subject to statistical verification and peer review before being committed in order to avoid false data being added to the census. As of April 2, 2019, this includes all official apgsearch-supported CPU symmetries for [[Conway's Game of Life]] as well as B38/S23/C1 ([[Pedestrian Life]]), B3/S01367/C1, B35/S136/C1, B3/S12/C1 ([[Flock]]), B3/S2/C1, and B3/S01357/C1.

==Catagolue as a generic pattern inventory==
Although primarily used for soup-searching in practice, Catagolue can be used as a generic pattern inventory/warehouse, as shown by e.g. the slow salvo data it collected (see above). Users are encouraged come up with their own rulestrings, symmetry types, and object codes:

:''[Catagolue] basically accepts anything that you choose to pass off as a rule name, symmetry type, and apgcode. If you make a search program which produces haul files for your favourite CA, then Catagolue will happily build a distributed census [...]''

:''The search program needn't even be a soup search: if you have a depth-first search program such as gfind or zfind, and you have a correspondence between positions in the search tree and alphanumeric strings (where prefixes correspond to ancestors), then you can conduct a distributed search for (say) width-20 c/6 spaceships using the existing Catagolue framework. If you incorporate all of zfind's command-line hyperparameters (period, offset, memory size, etc.) into the beginning of this string, then you can simply have a 'symmetry' called zfind whose tabulations will include things such as xq7, xq10, xq19 (potentially!), etc. And this will work without changing Catagolue in any way.''

::— [[Adam P. Goucher]]<ref name="post48707" />

This is simplified by the <tt>stdin</tt> symmetries of [[apgsearch]], which accept RLEs from standard input to be used in lieu of random soups. [[Arie Paap]] found a c/4 diagonal [[tubstretcher]] in this manner by piping the output of [[ikpx]] into apgsearch.<ref name="post70977" /> This was notable in that the tubstretcher could neither be found by ikpx (which can only find spaceships) nor apgsearch (searching random soups) in isolation.

===Glider syntheses===
{{alsosee|Tutorials/Glider syntheses#Submitting syntheses to Catagolue}}
Catagolue also contains a database of cheapest known [[glider syntheses]] of various objects (including pseudo-objects) retrieved from both [[Shinjuku]] and [[LifeWiki]], and displays them on the respective object page. A list of objects for which syntheses are available is compiled in the <tt>synthesis-costs</tt> [https://catagolue.appspot.com/census/b3s23/synthesis-costs symmetry] of B3/S23.<ref name="post74801" />

The [https://catagolue.appspot.com/syntheses "Syntheses" page] of Catagolue transcludes the <tt>synthesis-costs</tt> census and also includes a text box in which users can submit synthesis components in [[RLE]] form to be added to Catagolue's <tt>readsynth</tt> queue.{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/readsynth</nowiki></tt>}} These RLE files are automatically parsed and interpreted by Catagolue's thrice-daily update process, and added to the site if they contain new or improved syntheses.{{refn|group=note|As of August 2019, the synthesis submission box does not allow for [[linear growth]] syntheses to be submitted.<ref name="post81683" /> Instead, these must be added directly to the Catagolue database.}}

==Contributor engagement==
Contributors to Catagolue have user pages tracking their contributions to the main [[Conway's Game of Life|Conway Life]] census, B3/S23/C1.{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/user/<user name></nowiki></tt>}} In addition to providing an overview of number of objects submitted recently compared to other users, user pages list important discoveries and awarded badges.

Users are credited for discoveries if they find one of the first 20 occurrences of an interesting object: any [[spaceship]] (other than the [[glider]]), any [[oscillator]], any [[Infinite growth#Linear|linear growth]] pattern, or any sufficiently small ([[:Category:Strict still lifes with 14 cells|14-bit]]) or large [[still life]]. Certain other types of still lifes, such as [[Eater 2]] precursors, are also credited.

The following badges are currently awarded for contributions to B3/S23/C1:

* [[File:Conchita.png]] Conchita{{refn|group=note|The "Conchita" badge is named after [https://en.wikipedia.org/wiki/Conchita_Wurst Conchita Wurst], the Austrian singer who won the 2014 Eurovision Song Contest with the song "Rise Like a Phoenix".}}: find a soup containing a [[phoenix 1|phoenix]].
* [[File:GeminiTheBadge.png]] Gemini: discover a new [[twin bees shuttle]] variant.

* [[File:Trillionaire.png]] Trillionaire: contribute one trillion objects.
* [[File:Voyager.png]] Voyager: find one of the first twenty occurrences of a [[spaceship]].

Interesting new objects are additionally announced on Twitter by an unofficial Twitter bot.

==Backups==
Catagolue census data for the main [[Conway's Game of Life|Conway Life]] census, B3/S23/C1, is backed up remotely every day at 17:29;{{refn|group=note|Ramanujan time, after the [https://en.wikipedia.org/wiki/1729_(number) Hardy–Ramanujan number (1729)] of G. H. Hardy's and Srinivasa Ramanujan's.}} the first such backup was made on September 24, 2015. For other symmetries or rules, a remote backup may be instigated manually by calling the <tt>backupcron</tt> endpoint,{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/backupcron/<rule>/<symmetry></nowiki></tt>}} with the desired rule and symmetry. Remote backups can be viewed by appending the date to the main census URL.{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/census/<rule>/<symmetry>-<year>-<month>-<day></nowiki></tt>}}

Local backups of Catagolue census data may be made by calling the <tt>textcensus</tt> endpoint for the desired rule and symmetry.{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/textcensus/<rule>/<symmetry></nowiki></tt>}} The list of objects returned can be sorted by object frequency,{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/textcensus/<rule>/<symmetry>/sorted</nowiki></tt>}} but this should be avoided when possible to reduce server load.<ref name="calcyman20170129" /> It is also possible to restrict objects returned to a certain prefix,{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/textcensus/<rule>/<symmetry>/<prefix></nowiki></tt>}} or to query the number of objects, grouped by prefix and including a total.{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/textcensus/<rule>/<symmetry>/objcount</nowiki></tt>}}

==Limitations==
{{alsosee|apgsearch#Limitations}}

===Server===
Catagolue does not accept hauls exceeding 1 MiB; additionally, hauls must contains a minimum of 10,000 soups or 250,000 objects.<ref name="calcyman20160630" />

Each tabulation on Catagolue also has a maximum size of 1 MB imposed by Google Cloud Datastore; obscure objects will sometimes be deleted from these tabulations to meet this limit.<ref name="post64739" /> In December 2018, Catagolue switched to a new compression system, allowing certain [[:Category:Oscillators with period 2|period 2]] [[oscillator]]s to be manually readded to the D8_1 and D8_4 censuses without meeting the 1 MB limit.<ref name="post66653" />

===Web frontend===
Although Catagolue verifies that an object in a given rule behaves as specified by its code, the site makes no attempt to reject non-canonical codes (e.g. <tt>xp2_222</tt> rather than <tt>xp2_7</tt> for the [[blinker]]); furthermore, the site accepts various anomalous prefixes (e.g. <tt>xp0</tt> and <tt>xq0</tt>). No attempt is made to normalize or reject anomalous rules (e.g. "<tt>b33s23</tt>"), although a feature is planned to clear out censuses which do not adhere to the [[Catagolue naming conventions]].

Catagolue's <tt>hashsoup</tt> functionality, used for retrieving sample soups from the database,{{refn|group=endpoint|<tt><nowiki>https://catagolue.appspot.com/hashsoup/<symmetry>/<id>/<rule></nowiki></tt>}} only recognizes official square grid symmetries and D2_xo,{{refn|group=note|D2_xo is simply an orthogonal reflection of the equivalent D2_x soup for the [[Moore neighbourhood]], but functions as a distinct symmetry in hexagonal rules.}} and defaults to C1 for all others. Soups with symmetries exclusive to the [[hexagonal neighbourhood|hexagonal grid]] (i.e. containing <tt>C3</tt>, <tt>C6</tt>, <tt>D6</tt>, or <tt>D12</tt>) must instead be reconstructed using [[lifelib]].<ref name="post66638" />

==CiteDiscord template?==

Was thinking about this since [[User:Dvgrn]] added a Discord citation to the [[Max]] article. Would there be any objections to a template to cite the [https://discord.gg/BCuYCEn Conwaylife Lounge Discord server]? It is a public server, after all, and there have been quite a few notable discoveries and developments announced there over the years. [[User:Ian07|Ian07]] ([[User talk:Ian07|talk]]) 17:53, 16 February 2020 (UTC)
: Sounds good to me. I'd also like a Templates Cheat Sheet page under [[LifeWiki:Editor_pages|How to Contribute]] somewhere, probably just a section in [[Help:Templates]]. There are examples there of how to use some templates, but for many of them I currently just go hunting around randomly in articles until I find a good example of how it's used, and then copy and modify that. As the number of templates increases, this is starting to seem more and more, um, suboptimal. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 15:06, 17 February 2020 (UTC)

==Black ribbon==
Briefly popping out of the woodwork to mourn [[Richard K. Guy|Rich]] --- I had the idea of adding a black ribbon in the lower right corner of pages. This is added by a bit of code in <tt>[[MediaWiki:Common.js]]</tt>, with some supporting CSS in <tt>[[MediaWiki:Common.css]]</tt>. To turn this off again, simply comment out the line that says

$( document ).ready(function() {
console.log( "ready!" );
addMourningRibbon();
});

near the bottom of <tt>[[MediaWiki:Common.js]]</tt>. (Actually, commenting out the call to <tt>addMourningRibbon</tt> there will be enough.) Leave the rest of the code and the CSS in though; that way the ribbon can be reused next time there is a death in the community. (The link on the ribbon is set a little further up, and can easily be adjusted as needed.)

<s>N.B. --- the ribbon itself is a bit fiddly and doesn't always appear; I suspect this has to do with page caching, but I know too little about Javascript, Mediawiki and all that jazz to get to the bottom of it. Perhaps someone else who knows more can help.</s> Using jQuery (which, thankfully, is included in MediaWiki) fixed this, so we should now have a ribbon on all pages, always. [[User:Apple Bottom|Apple Bottom]] ([[User talk:Apple Bottom|talk]]) 10:13, 11 March 2020 (UTC)

: The black ribbon has been there for over ten days now; anyone want to suggest an appropriate total time period for it? I wandered over to <tt>[[MediaWiki:Common.js]]</tt> to see what would have to be done to turn it off, but found that I didn't have permission:
Permissions for editing of sitewide CSS/JS/JSON files were recently separated from the editinterface right.
If you do not understand why you are getting this error, see [https://www.mediawiki.org/wiki/MediaWiki_1.32/interface-admin mw:MediaWiki_1.32/interface-admin].
:Luckily I had permission to give myself permission, so I can now comment out the relevant line. The Internet suggests there are common 7-day and 30-day traditional mourning periods. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 21:32, 22 March 2020 (UTC)

::10 days seems fine to me. And yes, I had the same issue with permissions. Bit weird that MediaWiki doesn't give the relevant right to admins by default, but perhaps this is so that admins who're not aware of what they're doing won't accidentally break things.

== LifeViewer and RLE on OCA subpages ==

I was just looking at some experimental pages that [https://conwaylife.com/wiki/User:Ultimium Hunting/Ultimium] has put together for LeapLife. For example, the small knightship in LeapLife is called a "lepa", so it's presumably going to go under [[OCA:LeapLife/Lepa]].

But that brings up all kinds of questions. Look at [https://conwaylife.com/wiki/User:Ultimium/LeapWiki/Lepa Hunting's experimental Lepa page]. If RLE is added in the RLE: namespace for a lepa, and for all the other things Hunting will want to document, then those patterns will end up in the main pattern collection, right? That doesn't seem like such a good idea. It would be nice to be able to put RLE someplace where LifeViewer can still find it, but it doesn't end up in the main LifeWiki pattern collection. We only have a few non-Life patterns so far, like [[Bomber]], but it seems as if things could get out of control pretty fast if people want to add LifeViewer support for OCA pattern articles.

It seems like some different templates might be needed, to point to the alternate RLE namespace (if that gets created), and to get rid of irrelevant stuff like the links to Catagolue syntheses which won't exist for OCA patterns.

Thoughts on this? Would it be better to skip the templates, and just recommend that OCA patterns should keep their RLEs directly in the articles, as part of embedded LifeViewer text? Then I think the "RLE: here Plaintext: here" template won't work too well, and an alternate embedded-LifeViewer template for OCA patterns might be a good idea. (?) [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 16:09, 7 April 2020 (UTC)

: I think there should be a separate category, say OCARLE: and an option in the template |rle = oca for checking specifically under that header. Either that or one of the three other options:
:*Removing the pattern collection.
:*Creating a new wiki for other cellular automata.
:*Excluding all OCA RLE pages from the collection.

:: I agree with OCARLE. [[User:Ultimium|Ultimium]] ([[User talk:Ultimium|talk]]) 03:15, 30 May 2020 (UTC)

:Giving a quick search for RLE:bg gives 5 RLE pages as well, all in LeapLife. I think those should be excluded even if the others can't be, especially if I'm going to create more. (and Hunting's too, afaik there's only RLE:Lepa and RLE:Crawfish so that shouldn't be too hard) [[User:Bubblegum|Bubblegum]] ([[User talk:Bubblegum|talk]]) 18:25, 29 May 2020 (UTC)

: I don't object to either of these ideas, just want to point out that the latter option actually won't require the creation of a new template - if ''rle'' is specified instead of ''pname'', the links won't appear. [[User:Ian07|Ian07]] ([[User talk:Ian07|talk]]) 21:24, 7 April 2020 (UTC)

:: I prefer to use a seperate collection instead of the RLE embedded in the page, and a template for OCA patterns, for, um, for no reason. I mean they will be easier to access and manage. [[User:Ultimium|Ultimium]] ([[User talk:Ultimium|talk]]) 06:11, 8 April 2020 (UTC)

::: So far, the only good way to add patterns to OCA pages is what Hunting/Ultimium has done, e.g., with [[User:Ultimium/LeapWiki/Crawfish]]. But this currently means that the crawfish RLE is going to get added to the omnibus RLE collection downloadable from the main page. There are currently 66 OCA patterns scattered in among the 2300+ Life patterns. Might it be a good idea to split out all OCA patterns and provide a separate downloadable collection?

:::: I'm just mimicking Apple Bottom's [[User:Apple Bottom/Day & Night|Day & Night Wiki]]. I agree, we should split out all OCA patterns. {{unsigned|Ultimium}}

::: Also it might be worth adjusting the template used there somehow, to clearly label the crawfish spaceship in the infobox as being in a non-B3/S23 rule. (?) [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 13:49, 19 April 2020 (UTC)

:::: I like the current idea of adding a new OCA RLE category so they won't get lumped into the B3/S23 stuff. Yes, I think adjusting the infobox template to make it more visible that the pattern is not a CGoL pattern is worth doing. Also, there are some RLEs I'm using in some of my user pages for OCA patterns. They are [[RLE:Smosmos]], [[RLE:Sakaphipush]], [[RLE:Sakacapush]], [[RLE:Sakaw2]], and [[RLE:Sakasaladc8]] if I didn't miss any. [[User:Saka|Saka]] ([[User talk:Saka|talk]]) 13:42, 30 May 2020 (UTC)

== "Non-Lifelike" CAs -- cleanup suggested ==

[https://www.conwaylife.com/forums/viewtopic.php?p=93581#p93581 This post by BokaBB] got me looking at the rule pages that have been collected in the OCA namespace. [https://www.conwaylife.com/w/index.php?title=Category:Life-like_cellular_automata Category:Life-like cellular automata] includes several isotropic non-totalistic rules ([[OCA:GlideLife]], [[OCA:Goat Flock]], [[OCA:Just Friends]], [[OCA:Salad]], [[OCA:Snowflakes]], [[OCA:Tlife]], and [[OCA:Wlife]], so far, and I might have missed something.) There seems to be standard wording in all of these saying " ''{Rule R} is a non-totalistic Life-like cellular automaton". But this just plain isn't right: a non-totalistic CA can't be Life-like.

The standard wording links to [[Non-totalistic Life-like cellular automaton]], which shouldn't really exist because technically there is no such thing. I guess the right name for that article should probably be just [[Non-totalistic cellular automaton]], and "Life-like" should also be removed from [[Isotropic non-totalistic Life-like cellular automaton]] and [[Non-isotropic_Life-like_cellular_automaton]] (both the titles and the article text).

Does anyone have any objection if I do a bunch of editing to fix this, before the problem gets any worse? Or does someone really want to LifeWiki-officially redefine what "Life-like" means? The current definition is so widely accepted that it's even [https://en.wikipedia.org/wiki/Life-like_cellular_automaton on Wikipedia]: "Life-like" implies an outer-totalistic rule, so it's '''much''' more limited than the space of isotropic non-totalistic rules.

I'd like to add a couple of new LifeWiki categories (or have someone competent do it for me): one for "Other Cellular Automata" in general (Life-like '''and''' isotropic NT rules), and one for isotropic NT rules specifically. At the moment it seems kind of hard to find a category page for all OCA: namespace articles -- you can't just search for "OCA" or "OCA:" (right?)

If we want to be really brave, we could make the isotropic NT category something like "Iso-NT". If that caught on -- big "if" -- then there would finally be a short standard way to say "isotropic non-totalistic". Maybe someday people could just say "isont" or "anisont" and expect to be understood. ("Aniso-NT" would be the equivalent category for "anisotropic non-totalistic", but there doesn't seem to be any point in creating that category since nobody's come up with a rule worth naming in that rulespace yet.)

... If anyone '''does''' have an objection, please suggest something we could do instead! [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 16:40, 7 April 2020 (UTC)

: This is probably a bit late, but I think those bunch of edits are a good idea (Which it appears you have not done yet). And yes, I do agree with defining "Life-like" as strictly for Outer-totalistic rules. Nope, you can't just search "OCA" or "OCA:", so yeah, it's currently impossible to find a category with all the OCA rules and nothing more: The "Life-like_cellular_automata" category doesn't include LTL and multistate rules, while the "Cellular_automata" category also lists a bunch of non-rule pages such as the general articles for rulespaces and the lists of rules investigated on Catagolue (which, aren't they obsolete?).

: Back on the definition of "Life-like", the inclusion of IsNT (Isotropic Non Totalistic) rules in the category of Life-like CA on the wiki will probably make new CA-Enthusiasts think that they are included in Life-like CA, which might have an effect on the forum.

:Also, over on the Discord the standard way to write "Isotropic Non-Totalistic" quicker seems to be "INT", and Heavpoot suggested (somewhat jokingly?) "AINT" for "AnIsotropic Non-Totalistic" (Perhaps "AiNT" is better), or we could just refer to them as "MAP Rules", although yeah, that isn't very good, as MAP includes Isotropic and totalistic rules as well. [[User:Saka|Saka]] ([[User talk:Saka|talk]]) 14:04, 30 May 2020 (UTC)

== Expanding Covered OCA Rules ==

Does anyone think that having articles for rules beyond Life-Like and Isotropic Non-totalistic should be on here, like Wireworld or Langton's Ant? These would still go under the OCA namespace, obviously. If anyone has any thoughts on this, that would be great. [[User:AforAmpere|AforAmpere]] ([[User talk:AforAmpere|talk]]) 5:02, 16 April 2020 (UTC)
: As far as I'm concerned, articles for any reasonably well-known rule would be very welcome in the OCA namespace. Wireworld and Langton's Ant definitely count as good examples.

: A big reason for inventing the OCA namespace was to provide a place for this kind of information, without accidentally cluttering up the "Life" part of the LifeWiki. [[User:Dvgrn|Dvgrn]] ([[User talk:Dvgrn|talk]]) 14:08, 19 April 2020 (UTC)

: I would like to contribute to these pages. [[User:Ultimium|Ultimium]] ([[User talk:Ultimium|talk]]) 02:00, 20 April 2020 (UTC)

Mmm, a similar discussion took place three years ago, see [[LifeWiki:Tiki bar/Archive/2017#Lists_of_rules]]. Speaking of articles for other cellular automata, how about those red links in the [[list of Generations rules]]? There are a variety of rules, and therefore it will be a huge amount of work if we want to write a page for each. Or should we consider their historical/current significance first? Need Generations experts here. (I dislike red links...Wait, I shouldn't show personal feelings here.) [[User:GUYTU6J|GUYTU6J]] ([[User talk:GUYTU6J|talk]]) 16:50, 13 May 2020 (UTC)

Tutorials/Finding rules

2020-05-28T05:58:42Z

Saka: rewording and a little bit

Welcome to the "big and scary" world of Other Cellular Automata! So, you want to create a nice rule. Really, there's no such thing as a "good rule" - different people are interested in different types of rules, but here are some general tips that should give you a general outline of what to do, because there are a lot of things you ''can'' do.

== [[Outer-totalistic]] rules ==

Firstly, please be aware that because the amount of outer-totalistic rules is small (relative to the amount of Non-totalistic rules), ''most'' of the interesting rules here are known. But don't be frustrated! There ''are'' some recently (at the time of writing) found-to-be-interesting Outer-totalistic rules like B378/S2458 and B35/S2467, and there will probably be more.

For outer-totalistic rules, one of the most basic principles is a lack of B1 and B2. (B0 also tends to create strange explosions.) Both are guaranteed to make your rule explosive.
B3 is also going to be a requirement, as it can be easily proven that without B0, B1 or B2, B3 is required for any patterns to escape their bounding boxes.

Aside from that, it is generally a matter of removing transitions if the rule is too explosive, and adding them if the rule isn't chaotic enough. It helps to get a feel for what each transition is like, for example S0 and S1 tend to have very strong effects and S4 tends to create very large still lives, in combination with other things.

== [[Isotropic non-totalistic]] rules ==

Non-totalistic rules allow greater flexibility than Totalistic rules, as they allow you to specify the specific arrangement of cells. For a list of those arrangements of cells, see the article linked above in the title of this section.

Analogous to outer-totalistic rules, your transitions to avoid are B0, B1e, B1c and B2a. 
You will also require one or both of B3i and B2c to make patterns able to escape their bounding box, 
and one or both of B2e and B3a to enable patterns to escape their bounding diamonds. 

Making isotropic non-totalistic rules can be difficult, however once you get a "feel" for it you will start to notice general trends in rule "characters", such as the typical behavior of rules with S1 and a lot of B2 transitions.

It helps to start first with a well known "good" rule, but otherwise there isn't much else to say. It may also help to think up a spaceship, attempt to make it work and then go from there, adding/removing transitions as required. Or, you could start with a small pattern, say, a pre-traffic light (one half of a [[pre-pulsar]]) and try to make a rule where it does something nice, such as become a large spark.

Saka: /* Outer-totalistic rules */ things, wording

Welcome to the "big and scary" world of Other Cellular Automata! So, you want to create a nice rule. Really, there's no such thing as a "good rule" - different people are interested in different types of rules, but here are some general tips that should give you a general outline of what to do, because there are a lot of things you ''can'' do.

== [[Outer-totalistic]] rules ==

Firstly, please be aware that because the amount of outer-totalistic rules is small (relative to the amount of Non-totalistic rules), ''most'' of the interesting rules here are known. But don't be frustrated! There ''are'' some recently (at the time of writing) found-to-be-interesting Outer-totalistic rules like B378/S2458 and B35/S2467, and there will probably be more.

For outer-totalistic rules, one of the most basic principles is a lack of B1 and B2. (B0 also tends to create strange explosions.) Both are guaranteed to make your rule explosive.
B3 is also going to be a requirement, as it can be easily proven that without B0, B1 or B2, B3 is required for any patterns to escape their bounding boxes.

Aside from that, it is generally a matter of removing transitions if the rule is too explosive, and adding them if the rule isn't chaotic enough. It helps to get a feel for what each transition is like, for example S0 and S1 tend to have very strong effects and S4 tends to create very large still lives, in combination with other things.

== [[Isotropic non-totalistic]] rules ==

Non-totalistic rules allow greater flexibility than Totalistic rules, as they allow you to specify the specific arrangement of cells. For a list of those arrangements of cells, see the article linked above in the title of this section.

Analogous to outer-totalistic rules, your transitions to avoid are B0, B1e, B1c and B2a.
You will also require one or both of these: B3i B3a
and one or both of these: B2c B2e
for patterns to be able to escape their bounding box/diamond.
Making isotropic non-totalistic rules can be difficult, however once you get a "feel" for it you will start to notice general trends in rule "characters", such as the typical behavior of rules with S1 and a lot of B2 transitions.
It helps to start first with a well known "good" rule, but otherwise there isn't much else to say. It may also help to think up a spaceship, attempt to make it work and then go from there, adding/removing transitions as required.

Saka: or, discuss on this page's talk page.

Ah! You want to write some Python? Well, look no further. Here you will learn the basics of Python-scripting in Golly™. Note that, while this won't function as a complete tutorial for Python, you should be able to still follow a bit even if you have no Python knowledge.

== Things to Install ==
Wait! You need to prepare some stuff first. You need:
*[[Golly]]
*Python 2.7+ (But not Python 3, since Golly doesn't support Python 3 as of the time of writing)
*Computer
*Keyboard
*Mouse (Optional)
If you are on a Mac, Python should already be installed (But alas, the author of this article doesn't have a "Mac", so the author is relying on information from others.). Once you have packed your stuff and prepared you can start your Pythoning adventure!

== What are we Going to Make? ==
For this tutorial we are going to make a very simple script that detects the [[period]] of the object on screen. Golly already has a built-in script for this exact thing (See oscar.py)but we are going to make it anyway because why not. We will start by detecting the period of an oscillator, then move on to making it able to detect the period of spaceships.

=== The Idea ===
The idea of this script is to take a the pattern and run it until it either repeats or crosses the set border of time. You'll understand later (hopefully) once we get into making the script. Let's draw an outline of our program in a flow chart (Note: The author has no idea how to properly draw a flow chart): 
[[File:Flow1.png]] 
So there, we have the flow our program is going to go in. Now we just need to translate that to Python. To start, open a new Python IDLE window, or any text editor, in fact.

== Let's get scripting! ==

=== Step 1: Setting things up ===
Let's set things up.

Believe it or not, Golly has it's own Python module (A python module is basically a set of functions)! It is used to make scripting easier and contains other useful non-Golly-related features such as easy dialog boxes without the need of the bulky tkinter commands. To import the Golly module, simply type

<pre>
import golly as g
</pre>

The 'as g' is not needed, but will make typing out the commands (Which are usually used a lot in Golly scripts) less tedious. Commands in that are packed into the Golly module can be found in Golly's help files under Help -> Python Scripting.

You could also do this if you want to omit "g." and make the commands even shorter, but beware of function name collisions:

<pre>
from golly import *
</pre>

We'll also need a variable for the period of the pattern, so put this in as well:
<pre>
period = 0
</pre>

=== Step 2: Is there a pattern? ===
There is a very simple way to test if the pattern is empty in Golly. If you read the Golly help files, you probably have found it already. If you haven't, it's <pre>g.empty()</pre>
The g.empty() command returns a simple True or False. It will return True if the pattern is empty and False otherwise. So, we first want to check if there even ''is'' a pattern to check the period of. Let's do that by using the Python if statement:
<pre>
if g.empty():
g.warn("No pattern!")
g.exit()
</pre>
This also shows us two other Golly commands:
*'''g.warn()''' opens a dialog box with the classing yellow triangle warning symbol with the specified message.
*'''g.exit()''' stops the script.

Saka: development version differences

So you've decided to search for patterns using [[Oscar Cunningham]]'s [[Logic Life Search]] tool. Excellent!

==Installation==

===Prerequisites===
Are you a Windows user? If so, you'll need a Unix-like environment.

# Start by installing [http://cygwin.com/ Cygwin]
# When prompted to choose which packages to install, make sure <tt>dos2unix</tt>, <tt>gcc-core</tt>, <tt>git</tt>, <tt>gzip</tt>, <tt>make</tt>, <tt>python2</tt>, and <tt>tar</tt> are all selected.
# If prompted, confirm that you also want to install any required prerequisities.

If you already have Cygwin installed, you obviously do not need to install it again, but make sure all the packages listed above are installed.

===Installing LLS===
You can now install LLS itself. The easiest way to do this is using a shell (i.e. command line); you can also download a ZIP file and unpack it using your favorite archiver, but you'll be using the shell to run LLS anyway, so you might as well get used to it.

LLS is published on [https://en.wikipedia.org/wiki/GitHub GitHub], which uses [https://git-scm.com/ Git] as its version control system. Don't worry, you won't have to learn how to use Git,{{refn|group=note|If you're interested in doing so, refer to Git's documentation. The [https://git-scm.com/docs/gittutorial tutorial] is a good place to start.}}, but you'll be using a few commands to download LLS and keep it updated.

Start by "cloning" the code so you'll have a full copy (don't worry, this'll only take a few seconds):

<pre>
$ git clone https://github.com/OscarCunningham/logic-life-search.git
Cloning into 'logic-life-search'...
remote: Counting objects: 73, done.
remote: Compressing objects: 100% (52/52), done.
remote: Total 73 (delta 29), reused 35 (delta 14), pack-reused 0
Unpacking objects: 100% (73/73), done.
$
</pre>

This'll create a subdirectory called "logic-life-search" containing LLS. No further compilation is required.

===Staying up-to-date===
LLS is still evolving; you may want to pull in new changes and improvements made by the author. To do this, use the "git pull" command (be sure to enter the LLS directory if you're not already in it):

<pre>
$ git pull
remote: Counting objects: 84, done.
remote: Compressing objects: 100% (32/32), done.
remote: Total 84 (delta 65), reused 71 (delta 52), pack-reused 0
Unpacking objects: 100% (84/84), done.
From https://github.com/OscarCunningham/logic-life-search
ac5758a..153f87e develop -> origin/develop
Already up to date.
$
</pre>

===Using the development version===
New features are first made in the "develop" branch of the program. By default, you're using the "master" branch; use the "git checkout" command to switch to a different one:{{refn|group=note|Despite the name, this is a local command that does not interact with the remote repository on GitHub.}}

<pre>
$ git checkout develop
Switched to branch 'develop'
Your branch is up to date with 'origin/develop'.
$
</pre>

To switch back to the stable "master" branch again, simply use "git checkout" again:

<pre>
$ git checkout master
Switched to branch 'master'
Your branch is up to date with 'origin/master'.
$
</pre>
Note that the development version has some differences with the regular "master" version. These differences are noted in the [[Tutorials/LLS#Development_Version_Differences|Development Version Differences]] section.

===Installing a SAT solver===
LLS works by converting a pattern search problem into a boolean satisfiability (SAT) problem and solving that using a SAT solver tool, so you'll need a SAT solver.

LLS currently supports three SAT solvers: MiniSAT, Glucose and Lingeling. We'll focus on Lingeling in this tutorial, as it appears to work best across different platforms, including Windows/Cygwin.

====Installing Lingeling====
Download Lingeling from [http://fmv.jku.at/lingeling/ its website]. You'll want the latest version; as of June 2018, that's [http://fmv.jku.at/lingeling/lingeling-bcj-78ebb86-180517.tar.gz lingeling-bcj-78ebb86-180517.tar.gz].

Next, extract the file you downloaded (version may differ):

==First steps==

===Finding 25P3H1V0.2===
For our first test, let's find [[25P3H1V0.2]],<ref name="post55778" /> a small [[speed of light|c]]/3 [[spaceship]] originally found by [[David Bell]] in {{year|1992}}.

Enter LLS's directory if necessary, and run the following:

<pre>
$ ./lls -S lingeling -m -b 16 6 -p 3 -x 0 -y 1

LLS converted our request to a problem Lingeling could solve, and Lingeling did so in less than 3 seconds. Impressive! Here's our result:

But what ''did'' we request? Let's take a look at the options we passed to LLS:

* <tt>-S lingeling</tt>: tells LLS to use Lingeling as its SAT solver. The default solver to use is Glucose, but we installed Lingeling and would like to use that.
* <tt>-m</tt>: tells LLS to look for a moving pattern, i.e. for the first two generations to be different.
* <tt>-b 16 6</tt>: tells LLS to create a blank search pattern with a size of 16×6. Without this, we'd have to have told LLS explicitly what our pattern should look like.
* <tt>-p 3</tt>: tells LLS to look for a [[period]] 3 pattern.
* <tt>-x 0</tt>: tells LLS to look for a pattern moving by 0 cells horizontally in each full period.
* <tt>-y 1</tt>: tells LLS to look for a pattern moving by 1 cell vertically in each full period.

There's a lot more options to LLS; run <tt>./lls -h</tt> to see them all.

===Finding Brain===
Let's try hunting for a different spaceship, [[Brain]].<ref name="post55792" /> Run the following:

40 seconds — not bad! Here's our catch:

{{EmbedViewer
|caption = [[Brain]]
|position = center

}}

We already know the <tt>-m</tt>, <tt>-b</tt>, <tt>-p</tt>, <tt>-x</tt>, and <tt>-y</tt> options from above. But there's one new one:

* <tt>-s "D2|"</tt>: tells LLS to look for patterns with a specific [[symmetry]]. We passed <tt>"D2|"</tt>, meaning we're interested in patterns that are mirror-symmetric about a vertical axis. The quotes around <tt>D2|</tt> are necessary to keep the shell from interpreting the pipe symbol, <tt>|</tt>, as a special character, and instead pass it to LLS unchanged.

Specifying a symmetry made finding [[Brain]] that much faster.

===Finding an alien (2,1)c/3 spaceship===
LLS can search different rules. It's not limited to [[Life-like cellular automaton|semi-totalistic rules]] either, and in fact you don't even need to specify the exact rule you're interested in. To demonstrate this, let's find a small [[alien]] [[spaceship]] moving at a speed of (2,1)[[speed of light|c]]/3:<ref name="post55864 " />

<pre>
$ ./lls -S lingeling -p 3 -x 2 -y 1 -i -b 6 6 -r pB1-c2345678/S012345678 --force_at_most 5

Most of the options passed to LLS are familiar by now, but three are new:

[[File:Neighborhood 1c.png|right|frame|<tt>B1c</tt>]]
* <tt>-i</tt>: tells LLS that the first generation of the pattern found must contain at least one live cell. We're not interested in empty solutions.
* <tt>-r pB1-c2345678/S012345678</tt>: tells LLS what birth/survival conditions we'll allow in our target rules. In <tt>pB1-c2345678/S012345678</tt>, the leading <tt>p</tt> tells LLS that the following is a partial specification, rather than a complete one. The trailing string, <tt>B1-c2345678/S012345678</tt>, describes the [[rulespace]] we'd like to be considered. Here, <tt>B1-c</tt> rules out the "B1c" subcondition. B1e, B2 to B8, and S0 to S8 are all allowed. Refer to [[Hensel notation]] for an overview over the various subconditions allowed; for an easy-to-use script for converting a given range of rules to the notation required by <tt>-r</tt>, see [[Tutorials/LLS#Finding the right parameter to pass to -r|§ Finding the right parameter to pass to <tt>-r</tt>]].
* <tt>--force_at_most 5</Tt>: tells LLS that the first generation of the pattern found must contain at most five live cells.

The last option is important; without it, Lingeling (and, by extension, LLS) might find a different pattern than the one above. There are many solutions satisfying the constraints we imposed, and only the first solution identified will be reported.

==Success -- now what?==
Let's assume that you have run your own search, and found something new and exciting. What now? You may want to report your discovery; perhaps it's known, perhaps not. Here are some good places to do so:
{{LinkForumThread|f=2|t=2031|title=Spaceship Discussion Thread}}
{{LinkForumThread|f=2|t=1437|title=Oscillator Discussion Thread}}
{{LinkForumThread|f=2|t=576|title=Thread for your unsure discoveries}}

There's one thing you should (probably) not do, and that's start a LifeWiki article on your discovery. If it's notable, chances are good someone else will.

==How do I...?==
This section collects helpful hints and tips on how to accomplish common tasks.

===Finding the right parameter to pass to <tt>-r</tt>===
LLS's <tt>-r</tt> option requires the target [[rulespace]] to be passed in what has been dubbed "Macbi partial" notation. Converting a pair of given "minimum" and "maximum" rules to this notation is not entirely straightforward; [[Rhombic]] has made available a pair of scripts (to be run inside and outside of Golly, otherwise functionally equivalent) to perform the necessary conversion.<ref name="post56139" />

Suppose that you want to search any rules falling into the rulespace demarcated by B3/S2-i34q ([[tlife]]) and B35e8/S2-i34ceq6i7e8. Running Rhombic's script and entering both values yields <tt>pB3aceijknqry5-acijknqry8/S2acekn-i3aceijknqry4q-aijknrtwyz6-acekn7-c8</tt>, so this is the option you should pass to <tt>-r</tt> when running LLS to perform your desired search.

==Troubleshooting==
This section collects common and not-so-common problems you may run into, and suggestions on what might have gone wrong.

===Unsatisfiable===
Problem: LLS says the search is unsatisfiable, i.e. has no solution.

====Bounding box too small====
Possible explanation: the bounding box you specified was too small to accommodate the full evolution of the final pattern. For example:

<pre>
$ ./lls -S lingeling -r B2en3ij4a5e7e8/S1c2cek3-a4aiqw5aky -b 10 10 -p 55 -x 9 -y 0 -i

Time taken: 0.0 seconds

Unsatisfiable

$
</pre>

We asked for a deplacement of 9 <tt>-x 9</tt> while also requiring the entire pattern to fit into a 10×10 bounding box (<tt>-b 10 10</tt>), and LLS and Lingeling quickly determined that there was no way that a period-55 (<tt>-p 55</tt>) pattern meeting both these criteria could possibly exist.

Solution: Passing a larger bounding box should help.

====Incompatible line-end characters====
Possible explanation: you used an input text file created on Windows, which uses different line-end characters than what Unix-based tools expect. Windows uses <tt>\r\n</tt>; Unix uses just <tt>\n</tt>, and LLS is interpreting each line of your input file as representing an entire generation of the pattern.<ref name="post56049" />

Solution: this should be fixed in the "develop" branch of LLS; see [[Tutorials/LLS#Using the development version|§ Using the development version]] for instructions on how to switch to that version. Alternatively, use the <tt>dos2unix</tt> tool to convert your input file to Unix line endings:

<pre>
$ dos2unix.exe input.txt
dos2unix: converting file input.txt to Unix format...
$
</pre>

== Development Version Differences ==
The Development version of LLS has some differences with the regular version in it's commands. It might be a bit tricky to figure out how to use the development version, so here's a quick guide:
*Parameters for the search are now passed into the <tt>-s</tt> option, so for example, while in the regular version search parameters would be written, say, <tt>-p 4 -x 1 -y 2</tt>, in the development version, they would be written <tt>-s p4 x1 y2</tt>
**Symmetries are also now in the <tt>-s</tt> option, so <tt>-p 4 -x 1 -y 0 -s "D2-"</tt> in the regular version would be <tt>-s p4 x1 y0 "D2-"</tt> in the development version.
*The <tt>-i</tt> option is gone. A replacement for it is the <tt>-c</tt>, which forces the first two generations of the pattern to be different. If you wish to tell LLS to make the first generation have at least one live cell, use <tt>-p ">1"</tt>, which says "Make sure the population is greater than ( ">" ) one ( "1" ).
*The <tt>--force_at_most</tt> option is gone as well. Use the <tt>-p</tt> option.

Saka:

[[Andrew J. Wade]]'s life slice spaceship search (or LSSS for short) is the latest shiny new search program for finding ships in Life and Life-Like (Although not non-totalistic) CA. It's by far the fastest search program for Life-like (Isotropic non-totalistic) CA, so it's pretty recommended.
== Installing ==
=== Prerequisites ===
LSSS requires a unix-like command line (The author of this Tutorial used WSL [Windows Subsystem for Linux], to install WSL, go [https://docs.microsoft.com/en-us/windows/wsl/install-win10 here]) and [https://www.rust-lang.org/ Rust], as detailed on it's [https://gitlab.com/andrew-j-wade/life_slice_ship_search gitlab page]. 
Click and follow all the links in the above sentence. 
Also be aware that large LSSS searches require quite a lot of disk space. A width 15 search, for example, requires over 60 gigabytes of disk space.

=== Getting the Thing and Compiling ===
First, clone the GitLab repository with the following command:
git clone https://gitlab.com/andrew-j-wade/life_slice_ship_search.git
Next, go into it's directory by typing
cd life_slice_ship_search
To compile the program, run the following command:
RUSTFLAGS='-C target-cpu=native' cargo build --release
 
Because of how much disk space is required for LSSS (as mentioned in the "Prerequisites" section), the author suggests to move the LSSS folder and files to another drive with more space, if available.

'''Important note''': If you are using WSL, the author suggests to move the LSSS folder out of the root folder. The root folder is located at the directory <tt>C:\Users\<username>\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState</tt>. This is because deleting and modifying files within the root folder from the normal Windows File Explorer can screw up permissions.

== Doing A Search ==
Navigate to the LSSS folder and look for the file <tt>search.sh</tt>. Open it with your favorite text editor. At the start you'll see some options you can change. Most of these are pretty straightforward, but let's take a look at each of them:
*'''margin''': This is the width you want to search at. However, add one more to this margin value if you are searching for asymmetric ships (For example, if you want to search for a width 10 asymmetric ship, you want your "margin" value to be 11).
*'''midline''': This is the symmetry you want your search to be. There are three commented out and one not commented out. They're pretty self-explanatory, there's one for even symmetry, one for odd symmetry, one for gutter symmetry, and one for no symmetry. Pick one and comment out the rest.
*'''parms''': This is where you put in the velocity and rule you want to search for and in. Should be pretty straightforward. If you're new to the velocity notation, it works like this:
(dx,dy)c/period
"dx" is "delta x", or, the x displacement after <period> generations. 
"dy" is "delta y", or, the y displacement after <period> generations. 
Or, to put it simply, a ship with velocity (dx,dy)c/period will travel dx number of cells to the right and dy cells down after period generations (some programs flip up-down and left-right but that doesn't really matter).
*'''seedcolumn''': This parameter sets the first row of the search. You don't really need to worry too much about this. Leave it at 00 for now, it will be discussed later.

Just to demonstrate, let's search for a c/7o (In the velocity notation, (1,0)c/7) in Diamoeba (B35678/S5678). To do this, set the <tt>parms</tt> variable to
--velocity (1,0)c/7 --rule B35678/S5678
this will search for a ship that moves one (1) cell horizontally every seven (7) generations in the rule B35678/S5678.

Saka: better words... ... ...

Ah! You want to write some Python? Well, look no further. Here you will learn the basics of Python-scripting in Golly™. Note that, while this won't function as a complete tutorial for Python, you should be able to still follow a bit even if you have no Python knowledge.

== Things to Install ==
Wait! You need to prepare some stuff first. You need:
*[[Golly]]
*Python 2.7+ (But not Python 3, since Golly doesn't support Python 3 as of now...)
*Computer
*Keyboard
*Mouse (Optional)
If you are on a Mac, Python should already be installed (But alas, the author of this article doesn't have a "Mac", so the author is relying on information from others.). Once you have packed your stuff and prepared you can start your Pythoning adventure!

== What are we Going to Make? ==
For this tutorial we are going to make a very simple script that detects the [[period]] of the object on screen. Golly already has a built-in script for this exact thing (See oscar.py)but we are going to make it anyway because why not. We will start by detecting the period of an oscillator, then move on to making it able to detect the period of spaceships.

=== The Idea ===
The idea of this script is to take a the pattern and run it until it either repeats or crosses the set border of time. You'll understand later (hopefully) once we get into making the script. Let's draw an outline of our program in a flow chart (Note: The author has no idea how to properly draw a flow chart): 
[[File:Flow1.png]] 
So there, we have the flow our program is going to go in. Now we just need to translate that to Python. To start, open a new Python IDLE window, or any text editor, in fact.

== Let's get scripting! ==

=== Step 1: Setting things up ===
Let's set things up.

Believe it or not, Golly has it's own Python module (A python module is basically a set of functions)! It is used to make scripting easier and contains other useful non-Golly-related features such as easy dialog boxes without the need of the bulky tkinter commands. To import the Golly module, simply type

<pre>
import golly as g
</pre>

The 'as g' is not needed, but will make typing out the commands (Which are usually used a lot in Golly scripts) less tedious. Commands in that are packed into the Golly module can be found in Golly's help files under Help -> Python Scripting.

We'll also need a variable for the period of the pattern, so put this in as well:
<pre>
period = 0
</pre>

=== Step 2: Is there a pattern? ===
There is a very simple way to test if the pattern is empty in Golly. If you read the Golly help files, you probably have found it already. If you haven't, it's <pre>g.empty()</pre>
The g.empty() command returns a simple True or False. It will return True if the pattern is empty and False otherwise. So, we first want to check if there even ''is'' a pattern to check the period of. Let's do that by using the Python if statement:
<pre>
if g.empty():
g.warn("No pattern!")
g.exit()
</pre>
This also shows us two other Golly commands:
*'''g.warn()''' opens a dialog box with the classing yellow triangle warning symbol with the specified message.
*'''g.exit()''' stops the script.
