How do you simulate Non-Totalistic Isotropic rules in custom rule tables?
symmetries:rotate4reflect
Order: N,NE,E,SE,S,SW,W,NW
So if I want to have B3, I have to list every neighborhood of 3? Is there any way to simplify it with variables?
Yes, but then it gets even more complicated. Best off trying to put together Nutshell.

I'm fairly new to this CA stuff, but aren't there votes for pattern of the year in OCA and Life? When do they occur?

The start of the next year actually, or a few months after. (I'm looking at you, testitem.)

What is with B2a rules and Sierpinski Triangles? Why do most replicator-puffers cause them?

Code: Select all

x = 13, y = 11, rule = B2-ci7e/S3q5y

The Sierpinski triangle is the history of the simplest replicator (such as the one in B2a/S), so naturally most puffers of replicators (such as the first pattern) make them (each row of replicators further behind the puffer shows the next layer of the triangle), as do replicating puffers (the replicators leave debris where they are, and replicate into the next layer of the triangle). The question is not why B2a rules have a tendency to create Sierpinski triangles but why they have more replicators (which is pretty obvious: a line of 2 cells keeps going in the same direction, allowing it to potentially eventually create another one).
Any sufficiently advanced software is indistinguishable from malice.

Well, it's not just replicators that form them either, in the second example, an object is puffing tubs and barges in the shape of a Sierpinski, so what explains that?

The second pattern is basically an ordinary rule 90 replicator except that it moves. If you move each of the preblock units back 6 diagonals every 12 generations, you will see that it is fundamentally the same type of pattern.

Is there any program that can support searching semi-exploding rules in LtL? I want to find oscillators and a diagonal ship in the rule R2,C0,S4,B4. Its a very interesting rule which Kellie Evans named as the LtL rule with the most interesting dynamics in her thesis, but for some reason it seems no one has investigated it further.

I tried to use apgsearch on the rule, but it didn't seem to get anywhere on my computer. Most small patterns in the rule stabilize, except for one somewhat common exploding pattern, which causes most large-enough soups to never stabilize.

Any help would be much appreciated!

Lemon41625's Logic CA Search might be what you're looking for. I've seen people post decent results they found using it, but I personally know almost nothing about how it works, so if you have trouble you might want to post in that thread if you need any help. (I know Hunting suggested PlutoniumSearch elsewhere, which I also don't know much about beyond the facts that it exists and that Hunting wrote it.)

EDIT: Sorry for the double suggestion, ha ha. (I see Lemon41625 recommended their search program in the other thread only a minute before I submitted this post.)

PlutoniumSearch is basically gsearch (not gfind!) but without puffer engine detection and is much slower and supports search space "slicing" like CopperSearch.

I'm confused. How is that not a replicator? A replicator creates copies of itself. That pattern creates copies of itself.

I suppose you're right. It copies itself by a factor of two each time it copies. I suppose it is a replicator.

A non-monotonic spaceship is basically a spaceship whose frontend falls back in some generations. Such spaceships must have a period of at least 3.
B2n3-jn/S1c23-y is an interesting rule. It has a replicator, a fake glider, an OMOS and SMOS, a wide variety of oscillators, and some signals. Also this rule is omniperiodic.

Is there a such spaceship with a period of 2 in Larger than Life rules?
For example, there may be one that go forward two steps and then back one step.

By the way, some rules like JvN29 and Devore are really complex and don't have wiki articles.
Could you explain them?

Is it possible to complete this partial, if one matches the first nine rows of this phase? No matter how much ikpx2 widens, it can't get past depth 56, giving me evidence to suspect non-completability of this partial.

I've seen some rules with a d at the end of them and some people label them as deficient. What exactly is a deficient rule?
