ctak/include/cnn1986.c, branch lazy_queue An implementation of Tak and a computer opponent in C https://git.l-3.space/cgit/ctak/atom?h=lazy_queue 2026-08-28T18:37:41Z Trying to make things faster 2026-08-28T18:37:41Z tslil tslil@posteo.de 2021-06-01T19:20:48Z urn:sha1:0deb42134cb7f0ed6ec809c3de1052ab2dfe2235 I tried the following, but they all made things worse: - moving away from the singly-linked (tail tracking) list for actions by: + using an array zipper for a deque + using an array to poorly hold a floating deque - caching the results of generating move lists in the transposition table and then + copying the resulting list/zip/deque instead of generating it + applying the move-to-front without copying, but this made the search order worse. Presumably in this case shallower nodes were messing up the search tree with garbage moves? I think some of this is not supposed to happen, but i have just the right combination of poor evaluation function and naively ordered and cheap move generation that i'm in a local minimum here.

Ideally also this would be update per ply and we could avoid recalculating it entirely for every query -- though it's probably ``fast enough'' for now. Also, caching is WIP. Rename ct_k -> ct, IANAL but ... 2026-08-28T18:37:41Z tslil tslil@posteo.de 2021-02-05T21:49:14Z urn:sha1:ce09b6d94ac3dbf426e959b14fd7731001a003d1 Just some #weightgoals ;) 2026-08-28T18:37:41Z tslil clingman tslil@posteo.de 2021-02-01T04:33:39Z urn:sha1:328c8d1e3094a942d6a2edd933c9cc4ab09daab1 It turns out that while i was training on a 0/1 classification problem, i was using 2*eval - 1. Training using this function instead, and on bot-dominated game choices (chosen_player in extract.sh) seems to have given a better evaluation function. At the least, Morten's swindle doesn't work anymore.
