Re: Soup search results

It's most likely that /attribute can't find the discoverer because the haul in which it was discovered has already been auto-deleted - this is quite possible, as carybe was (up until a few hours ago) submitting hauls fast enough they get auto-deleted in less than 12 hours.

Re: Apgsearch games

This is an intrinsically unbalanced challenge, because B35/S135 is a totalistic rule and thus gets numerous built-in speedups that B36i/S234j does not. As a result, there is a wide difference in the searching speeds: on my computer, the former runs 30k soups/sec/core and the latter 700.

Lifelib can handle arbitrary neighbourhoods and combines with apgsearch, though apgsearch requires the neighbourhood to have at least rotate4 symmetry.

Not directly, but I think you could apgsearch alternating rules indirectly by generating ruletables for them and then apgsearching those ruletable rules via lifelib.
