Re: Golly 2.8 will support non-totalistic rules

Okay, since I am dumb and can't figure it out: what is the syntax for defining non-outer-totalistic rules?

Re: Is there any form that survives randomness? Detect and react

In Reliable cellular automata with self-organization , Peter Gacs proved the existence of a 1-dimensional cellular automaton which is computationally universal, and for which a universal computer can survive random perturbation if the error rate is sufficiently small. It's pretty complicated (it has...

Re: Geminoid Challenge

Also, Matthew Cook's construction of universal computation in ECA rule 110 stores information as the distances between spaceships rather than the presence or absence of spaceships themselves, so that idea isn't new either.

Re: A simulator with support for randomness

I know the CellularAutomaton command in Mathematica supports arbitrary transition functions, including pseudorandom rules. It seems to be optimized for one-dimensional rules, and doesn't do very well displaying animations of 2d rules the way Golly can. You also can't get it for free.

Re: Wireworld JvN

I just realized something: OR gates cannot be synchronous. This means that unless if we can find a conditional 2-gen advancer to fix the problem, this rule will be inevitably worse than the original Wireworld. I believe this is what you are looking for: I already posted an OR gate above... looking ...

Yea... the interesting thing about that device is that when switching the cell on, the electron will continue in a straight path unaffected, while when switching the cell off, it is destroyed. This can be used to make a very long period oscillator. For example: x = 20, y = 20, rule = wireworldjvn2 2...

So, it appears we now have a working glider synthesis and a glider destruction for the snark. That should lower the size of the geminoid significantly.

Indeed, the width 13 already has a bounding box with an area of only 221. An interesting question: what is the smallest orthogonal spaceship (by some definition of "smallest") with speed lower than c/2? So far, by bounding box area, the leading contender is x = 5, y = 16, rule = B3/S23 4bo$2b2o$2b2o...
