Re: Thread For Your Unrecognised CA

@RULE B2-an3_S2ac *** File autogenerated by saverule. *** This is a two state, isotropic, non-totalistic rule on the Moore neighbourhood. The notation used to define the rule was originally proposed by Alan Hensel. See http://www.ibiblio.org/lifepatterns/neighbors2.html for details @TABLE n_states:...

Re: A mashup of rules similar to Life

When I add them in, though, all cells die in every generation. Or at least for guntlife and reptlife, haven't tried with the other three. I see why. The new rule entries encode survival by specifying that the cells will die in certain conditions, and to do nothing in all others. Of course this mean...

Re: apgsearch v3.1

Is there any way to, uh, increase search speed? Running an instance of apgsearch on every core of your CPU, and getting more raw computing power. If there was a simple way to improve the speed of the search it would have been implemented by now. From what I've seen, apgmera already uses some pretty...

Re: On three-dimensional cellular automata

The other problem is that outertotalistic CAs seem to be less interesting overall anyway. There don't seem to be any programs for isotropic 3D rules currently, though coming up with a notation for that sounds like a nightmare, but that might make it possible to find interesting rules. Then again, fi...

Re: Spaceship Discussion Thread

One problem with the Pi wave stabilization problem is it's hard to stabilize it from the back . If there was a way to do that with a stream of spaceships then it could be possible to make a wave ship that synthesizes its own supports. But pi waves have a really low period for this sort of thing, so ...

So far, nobody has found a way to do universal construction. Right now, the best hope for something like tha...

Re: Spaceship Discussion Thread

Although I'm not experienced with building helices to be specific periods, I think I have to agree with the above: to actually gain over the 11c/24 burn reaction, the amount of time spent burning must be very long relative to the lengths of the fuses. However, I do believe there is room for improvem...

One thought I had, which might (if it pans out) alleviate some of the problems, is that if there is a single way to generate a new track that is phased or positioned relatively prime to the original ones, then instead of rephasing a single track a bunch and hoping there's some rake for one of those ...

Also, have you tried taming that 27c/74? It's pretty similar to the 17c/47 No, not really, at least in the spaceship building details. The 17c/47 produces extremely clean debris which can easily be interacted with without damaging the engine, while the 27c/74 seems more fragile, not to mention that...

But, what about a ship from taming the 2D replicator? Is that even possible? I've actually looked into this and it seems possible. However, it will likely end up as a sort of engineered spaceship, based more on waves than crawlers. The idea is that the wave pieces can connect in many ways, in some ...

Re: A mashup of rules similar to Life

As it turns out you're right: alife differs in two transitions, not just one. It's actually B3/S234iw, not B3/S234w. Since I already implemented this fix to verify, I figure it's best to share that in this case. So here's the updated rule: @RULE RainbowLL @TABLE n_states:17 neighborhood:Moore symmet...

Re: B34tw5y/S23

The 2D replicator might actually count as a failed 2D replicator - After about 8900 to 9000 generations, the debris has caught up and actually engulfed the replicators by producing more debris in front of the advancing replicator wall. Any more new 'copies' that appear after this point are the produ...

Since the above rule is closely related to the extremely oscillator-fertile B2ce3ai/S23 rule, I would not be surprised if it turns out to be omniperiodic as well.
