Re: Spaceships in Life-like cellular automata

I've been running sweeps of OT rules for some time now to both get new ships and see if there are any interesting statistics when it comes to the prevalence of different speed ships at different widths. It's hit a point where I can't really do any more searches across every B3 rule in a reasonable a...

Re: Thread for basic non-CGOL questions

Is there a known Isotropic Totalistic / Non-Totalistic rule that can be made to explode at a relativistic speed (speeds between c/2 and c) in all directions. By "be made", I mean that it is ok to specify a pattern, but it has to chaotically explode at a relativistic speed forever (Without any c exp...

Re: Spaceships in Life-like cellular automata

It's nothing too technically impressive; I wrote a quick python script that iterates through all rules starting in B3 and runs gfind at a given speed/width for each one. It saves the rule/width if there's a spaceship found at that iteration so it can skip over that rule when searching on a higher wi...

"Life-like" cellular automata are traditionally defined as being outer-totalistic, so B2-a5/S1e2-a35678 wouldn't count. (I think a fair number of people these...
