Any ideas to complete it? Can I use something like a regulator?

Actually, it is a working sawtooth with minimum repeating population 223. The advancing spaceship has speed 8c/17, the gun fires a spaceship with speed c/2, and the fuse formed afterward has speed 25c/52, which yields an expansion factor of 841/25 = 33.64. The first five minima occur at generations 89, 2027, 67205, 2259797, and 76018649.

My best guess is because the form that I'm used to looking 'for doesn't show up in this rule, so I suppose that you are correct because I would have recognized its predecessors had I memorized them.

How do I convert a binary string to base64 encoding for MAP rules? All I can find online is converting text to base64 encoding.

The rule I'm proposing is actually quite simple: it's Seeds, except B2a only works in half its configurations (with C4 symmetry), hopefully making it nonexplosive.

This diagram is just for visuals; it's not meant to be run.

Code: Select all

x = 23, y = 13, rule = LifeHistory
A2B2.B2A2.3B2.3B$ACB2.BCB2.BCA2.BCB$3B2.3B2.2BA2.2AB3$2AB2.2BA2.3B2.

That's not a question. Could you please reserve this thread for questions (and answers to those questions)?
Also, in general, simply saying that a rule is good or interesting is not very helpful. If you show us the structures that it has that make it good or interesting (in the appropriate thread), that would be better.

How do I make a ruletable and what does everything do in one?

EDIT by dvgrn: A basic question like this fits better here than in a whole new thread under Website Discussion. Please try to limit the number of new threads, and the number of new one-liner posts without much content, that you create per day. People are starting to report some of them as being a bit too noisy for these forums -- "noisy" as in "low signal-to-noise ratio".

Have you seen the wiki tutorial? That might be the best place to learn about ruletables quickly.

EDIT:
re: movement to thread, why not the thread for basic non-CGoL questions?

EDIT by dvgrn: Yup, that is obviously what I should have done.

Some of the code in MAPper.lua might help, if you don't mind Lua instead of Python.

What it does is to create all 512 neighborhoods and actually run them for one tick in Golly. Then it creates a binary string representing the unencoded MAP string, and then it base64-encodes that string.

There's some extra complexity due to Golly not actually running the rule that it's supposed to sometimes, to avoid strobing effects. But the base64-encoding part should be fairly easy to extract.

Can someone tell me the string for each transition in a ruletable? I really need it!

Posted: **March 25th, 2021, 6:29 pm**

Please don't create a new thread every time you have a question like this. It clutters up the forums.

As usual with these types of questions, the first step would be to check LifeWiki, which has a table. There was an image somewhere with the same list but I forgot where. (this is assuming you are referring to non-totalistic rules, not ruletables.)

If you use them enough, you'll eventually memorize them all and the thought that they could have been assigned any other way will become pure nonsense. Don't let the task ahead daunt you!

If you meant "how to write transitions in rule tables", there's a guide somewhere. Basically, a transition looks like this (in smaller neighborhoods, there will be less transitions):

Code: Select all

center,N,NE,E,SE,S,SW,W,NW,final

This means that a cell in state "center" (they are numbers) surrounded by a given pattern of other cells will become the final state.

Sure -- but this is a basic OCA question. It definitely isn't a question about Conway's Life or about the forum website, and even if it were it wouldn't need a whole new thread on the Website Discussion board. Please spend some time trying to understand why I moved this question to this thread instead (for the second time in a row) before you create any more threads, or I'll have to start trying to get your attention with a temporary ban.

If you're building rule tables by hand (though I'm not sure why you wouldn't just use one of the scripts) then you'd just use the lists of ones and zeroes inside the brackets. Example: to build a table for B6k/S7e, you'd just look at these lines:

"6k" : [1,1,1,1,0,1,1,0], # N, NE, E, SE, SW, W
"7e" : [1,1,1,1,1,1,0,1], # N, NE, E, SE, S, SW, NW

"B" means a cell is being born, so it starts with state 0 and ends in state 1. The rule line is:

0,1,1,1,1,0,1,1,0,1

"S" means a cell is surviving, so it starts with state 1 and ends in state 1. The rule line is:

1,1,1,1,1,1,1,0,1,1

The symmetry that the table would need to define to use these strings would be 'rotate4reflect'.

But that doesn't imply that those are the only ones.

For margolus media that can have the cool oscillators, I know of three other types.

That looks like a rake — an oblique rake to be precise, with a speed of (37,23)c/189 if I'm counting right. It fires three different spaceships: forward gliders, backward gliders, and (semi-backward? idk what to call the direction) 34c/128 orthogonal ships.

Yes. Why wouldn't it be? It's even more passive then CGoL.

I have a question, Is there no planning 5s project only for B0 INT rules? Or modified version of matchpatt2.py for B0?

Posted: **April 10th, 2021, 11:13 am**

Is nonexplosive B1c possible? I've always assumed no, but my own pattern made me reconsider:

Code: Select all

x = 1, y = 1, rule = B1c2ci3r5i/S1e2a3i4c
o!

EDIT: Here's some work towards doing so. The nonfillers collide but don't explode. They sadly do explode when the four of them all collide.

Code: Select all

x = 82, y = 21, rule = B1c2cin3cer4r5i/S12ac3iq4cnw5a
10bo9$81bo$o10$70bo!

Here, they don't explode at all.

Code: Select all

x = 84, y = 82, rule = B1c2cin3cer4r5i/S12ac3iq4cnw5a
