### Re: A Survey of Small Rulespaces

Doubleposting but I feel that this warrants a doublepost. Pruning rulespaces It would make sense to treat the semi-totalistic condition A0 and all conditions that are a subset of semi-totalistic condition A1 as untoggleable, as B0/Dn (where n is the neighbour count in the neighbourhood) rules are ge...

### Re: HR1D (1-Dimension Rulespace)

Double posting, but it's been a month. Behold, a 2-state 1D rule which is semi-totalistic under the (maximally symmetric) 1D neighbourhood where: - two neighbours are at distance 1 from the central cell - two neighbours are at distance 3 from the central cell with five small unadjustable ships of fo...

### Re: A Survey of Small Rulespaces

One reasonably small space is "2-state isotropic CA on the hexagonal tiling using honeycomb neighbourhood, and with the added restriction that the current state of the middle cell is not considered when deciding on its future state". [...] You are right, I didn't consider the class of isotropic cel...

### A Survey of Small Rulespaces

I have been pondering about the question: what rulespaces are small enough such that every rule in it can be explored systematically in a reasonable amount of time, and if so, what objects can they contain? This question is ill-defined (depending on what 'systematic' and 'reasonable' means), but I s...

### Re: Patterns that grow by 1 cell per generation

It is trivial to make one-per-generation patterns (and by extension, n-per-generation patterns where n is some natural number) using guns or wickstretchers. Like you showed, many such patterns are clunky almost to the point of being contrived. A better use of this thread, arguably, would be to compi...

### Towards an Automatic Rule-Explorer
