Re: IntegerLife (R1,I8,S2-3,B3,NM)

Yellow (state 7) behaves exactly like standard Life. IntegerLife actually appears to be more stable than standard Life, since the extra states make it more similar to Highlife and Flock and eliminates many of Life's methuselahs. ... State 5 seems to be life as well ... 4 too ... Actually, the way I...

Re: IntegerLife (R1,I8,S2-3,B3,NM)

I'll also add in the condition that if a cell hits the max state (in this case 8, it dies) because I don't feel like waiting for an eternal for a 255 state ruletree to compile. I'm a bit more of a purist; in my own implentation, I supported 255 living states, and the program automatically halts if ...

Re: Soup search results

I think this P4 needs a name, since it is an edgy domino sparker, and it is statorless. .. Mark Niemiec's database has it as " 24-bit P4 #1 ", no synthesis; pentadecathlon.com calls it 24P4.1 . Catagolue has one C2_4 soup for xp4_g880anziaw5kze5011 but the oscillator shows up early, so converting t...

Re: Soup search results

I believe that that's the mod, not the period. Wiki says that block laying switch engine is period 288. Edit: Or maybe that's the period of the population growth, I don't know. Yes. When it finds growing patterns, apgsearch ignores the pattern image itself, and only concerns itself with the populat...

Re: Thread for your unsure discoveries

Not being able to complete the oscillator is frustrating, but I suppose that a significant proportion of attempts to do something in Conway's Game of Life end that way, and yet we persevere. I suppose that part of the difficulty is that I still haven't developed a sense of what things are worth try...

Why is lightbulb considered a billiard table? I can easily draw a path from a rotor cell to a cell outside its bounding box, indicating that the rotor isn't 100% enclosed by the stator. It depends on whether the rotor is ever exposed to the outside. Live stator cells obviously block this. However, ...
