Cellular automata
« on: January 30, 2011, 06:36:56 pm »
Does anyone have an interesting CA that they like?

This is one of my favorite 1D CA (because of its Turing completeness) and it was generated by the first Axe program I ever made. Rule 110:

That one is interesting, although I haven't fully understand how it can be turing complete. Never thought/read much about it though. Just saw somewhere it was turing complete and I know in a intuitive way what is turing complete.

I like Rule 30. Deterministic randomness FTW.
Game of life is great too.

As it turns out, Rule 110 has "structures" that can propagate down the grid at different angles. The multiple structures at different angles allow for "collisions" which can be placed properly to simulate other automata. That's basically how the proof goes.

Er, that is not 1D though in your pic at the top of this thread.

The rule is 1D in that only the current state of the system (a 1D line of pixels in that representation) is used to compute the next state of the system. The picture itself isn't 1D, but instead shows the evolution of the system over time.

* Spyro543 likes standard Game of Life.

But Seeds is pretty cool too.

(Powder Toy is an awesome cellular automata emulator. It has tons of types of automata.)

I like Game of Life and amoeba. <- I think amoeba is rule 0? I'll have to check.

Dang, I always thought this was powder toy :P thanks for also providing a link!

I love using golly to mess with Generations (multiple stages of life, rules are a little weird, up to 256 stages) and making fascinating wireworld-esque creations.
