A '''soup''' (or '''broth'''<ref>{{Cite web|url=http://sourceforge.net/forum/forum.php?thread_id=1900952&forum_id=467856|title=Optimal Broth|accessdate=June 16, 2009|date=December 28, 2007|author=Ethan Wilson}}</ref>) is a random initial [[pattern]]. It may have different [[density]], [[symmetry]] and could cover the whole [[Life]] [[universe]] or be finite.

==Ash==
'''Ash''' (or less commonly '''junk''' or '''debris''') is the ([[stable]], [[oscillator|oscillating]] or [[spaceship|flying]]) outcome of a soup or reaction.

Experiments show that for random soups in Life in [[finite plane]] with moderate initial densities (say 0.25 to 0.5), the resulting ash has a density of about 0.0287{{citation needed}}. In infinite fields the situation may be different in the long run because of certain rare patterns, like long-living quadratic replicators (if any) that produce a large enough "colony" and survive knocking into ash.

==Sparse Life==
'''Sparse Life''' (also called, somewhat confusingly, '''early universe''' by [[John Conway]]) is the study of the [[evolution]] of a soup of vanishingly small density in an infinite universe, and as such a part of [[cosmology]]. Such a universe is dominated at an early stage by [[block]]s and [[blinker]]s (collectively known as "[[blonk]]s") in a ratio of about 2:1, with rare structures created by common [[methuselah]]s (e.g. [[R-pentomino]]es and [[pi-heptomino]]es). Much later it will be dominated by simple [[infinite growth]] patterns (e.g. [[block-laying switch engine]] and [[glider-producing switch engine]]). The long-term [[fate]] of a sparse Life universe is not certain.

==Soup search==
'''Soup search''' or '''soup searching''' is a method of searching for interesting patterns. It is done by running random soups in a specific [[rule]], followed by counting the results and tabulating them.

Soup search can be implemented into languages like C and Python easily, making it popular. It can also be done manually in [[Golly]], with default key ctrl+5 to randomize a selected region.

It was employed in the [[Achim Flammenkamp's census]], [[Andrzej Okrasinski's census]] and the [[Online Life-Like CA Soup Search]]. Currently large-scale soup searches are done with [[apgsearch]], you are welcomed to join via [[Tutorials/Contributing_to_Catagolue]].

== What is Conway's Game of Life? ==
[[Conway's Game of Life]] is not a traditional game; instead, it is a "zero player game" where the outcome is determined by the initial state. Specifically, Life is a [[cellular automaton]] developed by the eponymous British mathematician [[John Horton Conway]]. First, let's understand what cellular automaton means. Cellular automata consist of a grid of cells (in Life's case, a grid of squares) that change state every generation based on the state of neighboring cells. Cellular automata can range from extremely complex, with dozens of states and many rules governing the cells' behavior, to extremely simple. Life, thankfully, falls on the simpler side. In Life, cells only have two states, on or off. The state of a cell is determined by the 8 neighboring cells surrounding it. Knowing this information, Life's rules can be described very succinctly;
* If a living cell has 2 or 3 neighbors, it will survive.
* If a dead cell has exactly 3 neighbors, it will be born.
* All other live cells die in the next generation, and all other dead cells stay dead.

Conway developed the Game of Life because he was interested in creating simple cellular automata with complex and unpredictable behavior. Despite being extremely simple and wholly deterministic (in other words, there is no randomness involved), Life has warranted 50 years (and counting) of intense study based on its properties.

There are three basic kinds of patterns in the Game of Life:
* [[Still lives]], which do not change from generation to generation and are generally uninteresting, but sometimes interact with other patterns in a useful way
* [[Oscillators]], patterns that repeat after a number of generations
* [[Spaceships]], patterns that move indefinitely across the board.

There exist a whole range of other patterns, however. For example, [[puffer|puffers]] are spaceships that leave a "trail" of debris behind it, and [[gun|guns]] are patterns that repeatedly "fire" spaceships.

== Why is Conway's Life interesting? ==
Firstly, it is important to examine what Conway was looking for when he made the Game of Life. Conway wanted to avoid two common types of cellular automata - those that collapse into static or predictable patterns almost immediately, and those that violently explode into uncontrollable chaos. Instead, he wanted it to be highly difficult to determine whether an initial pattern would survive, keep expanding, or die out. While we now know that the vast majority of small, chaotic patterns eventually stabilize, many of them take hundreds or thousands of generations to actually do so. This makes Life a clear example of order emerging from chaos, as well as an example of complex behavior emerging from simplistic rules.

Additionally, many small patterns in Life can react with other patterns, enabling the construction of engineered patterns. In fact, it is possible to build a computer in the Game of Life, and it has been long proven to be Turing Complete (in layman's terms, Life is theoretically capable of computing anything your computer can). Many small patterns have non-obvious uses. The [[glider]], the smallest spaceship in Life, can be used to construct other patterns and can also function as a memory tape. The [[block]], a 2x2 cube, has many reactions with other patterns and is used in many guns. There are many small still lives known as [[eaters]] which can stabilize various patterns and destroy, or "eat", spaceships. Using relatively simple reactions, many things can be constructed, such as [[Unit Cell|patterns that simulate Life in Life]] and [[pi calculator|a computer that calculates and displays the digits of Pi.]]

Another important problem that interested Conway was the existence of a self-replicating pattern in Life. While we now know that [[Linear propagator|several]] [[0E0P metacell|replicators]] exist, they are all extremely large and carefully engineered patterns. Conway's initial interest was inspired by the fellow mathematician John Von Neumann, who created the first replicating pattern in a cellular automaton. However, Neumann's pattern used an extremely complex rule with many states and arbitrary rules, and the construction of a similar pattern in a more "naturalistic" rule was of great interest to many.

[[User:Saka/Gemini_Pages/Tut:LSSS]]
{{DISPLAYTITLE:life_slice_ship_search}}

[[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.

hi, Moderators. I believe WSL is easy to use than cygwin. And it is more convenient to 'install'.
idk whether some of the lifewiki tutorial is obsolete. but at least it should clarify WSL is better alternative to cygwin (since win10 have occupied more than 50% market share)

post a link to saka's tutorial

prao:(discord)
maxwidth is the width of a single row, margin is the width of the entire pattern.

margin 15 and maxwidth 47 runs the same as margin 15 and maxwidth 15 — margin needs to be > maxwidth for floating rows to work

Also, recently for floating-row searches I have been setting margin=98 and only changing maxwidth — again, doing that means you need to change every time 27/28/29 appear in search.sh to 97/98/99
