Statorless p262:

P228 and P260 statorless oscillators endemic to this rule:

I did, ok.




Also, could you update the thread title, since the current name of the thread doesn't suggest it's about B34k/S23 (honestly, the current title sounds like some weird non-vanilla or generations rule)


4K Life is the name given to this rule. Would “4K Life (B34k/S23)” be a better ...

The 323: A 32-bit computer by blah capable of playing Tetris. One of the most remarkable works in cellular automata I've even seen, supplied with detailed documentation like a real circuit board, manuals, programming tools, etc.

As far as I can tell, there is no plausible consistent way to interpret '4z' as denoting a transition .

Moreover, the code snippet you posted after the quoted sentence appears to list eight different rules , making things even more confusing than they were before.


Technically correct or not ...

That would be a truly masochistic endeavor. 86x is one of the most awkward CISC architectures in existence. ARM, SPARC, RISC-V, MIPS, Alpha are much better designed. Being popular does not necessarily mean good. The same applies to OSes. If someone would try to implement a modern OS in a CA, that ...

Extremely impressive!

How do you make the display visible in Golly though?

A 90c/180 orthogonal spaceship in a non-isotropic version of Day & Night that preserves rotational, but not mirror symmetry, becomes a puffer when flipped.

The entire RuleLoader ruletable represents a cellular automaton .
Individual lines (such as "1, 0,1,0,1,0,1,1,1, 1") represent specific update rules of the cellular automaton.


Then again we have a contradiction of terms. Either people on this forum should call their rules CAs and not ...

Since you already have answered, I move my edit to the previous post here:

Here is another ruletable, Day & Night with a slight non-reflective change. Explaining it in a more verbose way, as you wish:


0 0 1 ? ? ?
1 0 1 ==> ? 1 ?
1 0 0 ? ? ?

1 1 0 ? ? ?
0 0 0 ==> ? 1 ?
0 1 1 ? ? ?

1 0 0 ? ? ?
1 ...

[...] EDIT : See the discussion below. Some terms above have been clarified. [...]


Note that most of cellular automata mentioned here aren't Life-like.
A Life-like cellular automaton is defined as a two-state outer-totalistic cellular automaton with the (range-1) Moore neighbourhood .

Very cool! Translating into a ruletable:

[...] I don't see a good reason why one would arbitrarily limit the notion of a "rulespace" (however it would be defined) to exclude non-isotropic CA. [...]


Because we intuitively expect an object that looks, say, like a rocket, to fly like a rocket in every direction. [...] In theory, of ...

Note: your post contains some damaged quotes with incorrectly specified author (making it appear as if you were talking to yourself).


Sorry for that! Fixed.


While recent exploration on these forums is focused on two-dimensional isotropic cellular automata (and on a small subset of those), I ...

What software (if any) did you use to produce this collection? I've found stable reflectors and splitters by playing manually with still-lifes. I suspect much more efficient ones could be found automatically.


Here are some 'interesting' things that the small 'U' spaceship can do with still lives ...

"Symmetry" in this sense isn't a property of the evolutionary sequence.


It is a property of rulespaces, not of evolutionary sequences. For example, there are many non-isotropic rules that allow a glider to evolve, if it's positioned in a particular way. But this is not what we usually view as ...

Additionally, I don't see how "symmetry" would be relevant here, can you explain that part? (I see relevance of neighbourhood.)


That's because the sets of transitions and thus rulespaces are different in different symmetries. There are only 2^18 outer-totalistic Life-like CAs, 2^102 isotropic ...

I believe that the rule B2en3aei5ac6aci7c8/S2-i3-k4c6a7c abundant with natural (2,6c)/14 camelships deserves its own thread. First, some definitions. Every pattern's evolution has its own rulespace with a given neighborhood and symmetry, which is a partially ordered finite set (unless we consider an ...

As for the claim about those rulestrings being "natural", I think that's misleading as well. Arguably it would be more natural to look at birth conditions and death conditions (those that are necessary for a given evolutionary sequence; those that are optional and can be added/removed; those ...

Of course it does, only for regular 2-state isotropic rules though. Not apgsearch as a client, but the Catagolue server:



The minimal set of transitions determines what transitions cause the object's behavior. For example, it is B3aijn/S2ae3jnr for a glider. If you follow the glider's movement ...

Every object or set of objects has its rulespace ranging from the minimal number of isotropic transitions that enable its exact behavior to the maximum. These two rules can be viewed as "signatures" of the given object. For example, Nikro has been recently apgsearching a rule that contains the ...

It is probably this (to be compiled with g++ and used with apgluxe compiled for a "stdin" census):

This unusual replicator can be easily used for gun construction, because it emit gliders that cancel each other:
