Re: A question to MCTS + NN experts

I am far from an expert, but here are some suggestions. You mentioned SL NN experience, but perhaps start with something simpler than chess. This repo I found to be very helpful (there is another one for chess after understanding Connect-4; the overall process is the same) https://github.com/Zeta36/...

Newer AMD 3000 cpus might be a better bet.

Re: Neural Net Endgame technique

I did some lone king training with small nets in September last year. It was with a version of Leela that might still have had the 50 move draw issue. In any case, an 8x1 net was fine for KQ or KR v lone K. However, for KBNvK an 8x1 net could not mate. Needed to be at least 16x2 for about 2/3rds win...

Turns out that it may not matter very much:

Re: Possible "real" hash collision

Maybe just try not testing for 3 on PV nodes, only at the root.

Re: Possible "real" hash collision

It might not be an issue in this case, but something that many engines (including Tinker) are surprisingly sensitive to is how to handle repetitions. I have found that the full 3-reps test should be used at the root, but anywhere in the search to score the 2nd rep as a draw and not to wait for the 3...

Re: Wb2uci adaptor

I understand your frustration. My point was that I suspect that the custom GUI is the issue. If you implement bare-bones UCI support and output per the UCI spec, the CCC GUI should be able to deal with it. Cutechess-cli is not the issue, of course. BTW, IIRC the Leela devs in the early days were som...

Re: Wb2uci adaptor

I might well be mistaken, but I seem to think the CCCC (is it 3 or 4 C's?) event GUI is a custom one, so even if it uses cutechess-cli, there may be UCI-only issues. While I personally prefer CECP for the control it affords to the engine, I eventually just added minimal UCI support to Tinker (not th...
