Re: apgsearch v4.0

can you make it work on non-x86-64 machines?
Any progress updates on how this is getting on? I remain intrigued by this rulespace.calcyman wrote:In terms of further rule families, the next one I intend to implement is outer-totalistic rules up to range 5.muzik wrote:Seems like a valid next step. The other two main ones I can think of would be B0 non-totalistic and LTL Generations.
I kind of hope that update will come to Golly as well, so we can actually run those rules.muzik wrote: Any progress updates on how this is getting on? I remain intrigued by this rulespace.
How about non-totalistic hexagonal rules? I would think those would be a fairly trivial variant of non-totalistic Moore neighborhood rules. The original HexLife from the Lifelines (B2om/S2H) is one of these, as is Callahan's hexagonal rule (B2o/S2m34H). These can, of course, be done using rule tables, but it seems like QuickLife and HashLife should be able to do these virtually free.calcyman wrote:In terms of further rule families, the next one I intend to implement is outer-totalistic rules up to range 5.
We have them for free already, don't we? Isotropic hexagonal rules must be a subset of anisotropic non-totalistic MAP rules, which are available both in LifeViewer and in recent versions of Golly.mniemiec wrote:How about non-totalistic hexagonal rules?

This script converts hexagonal isotropic (possibly non-totalistic) CA rules[1]
into the equivalent MAP rules[2]. It runs under both Python 2 and Python 3, and
can be used either as a stand-alone script (with the rules given as command line
arguments) or run directly in Golly. Posted[3] to github 27 Jan 2018 by vyznev[4].

...you are aware that catagolue and apgluxe have been handling LtL rules up to range 7 fine for the past seven months or so?77topaz wrote:I think using rules with ranges >1 would be too large a change for the current project, but maybe a separate database could be created for those rules.
That's not the problem. The problem is that we would have so many new speeds caused by adding these rules that it would make things more difficult.muzik wrote:...you are aware that catagolue and apgluxe have been handling LtL rules up to range 7 fine for the past seven months or so?
Yes, that was my point. I don't know what Catagolue and apgluxe have to do with it; I mean, they can also run B0 rules, but B0 ships aren't included in the main 5s project for the same reason. Still, I think separate side-projects for B0 and LtL ships could be done.danny wrote:That's not the problem.
