First an overview of features:
- 2606 (+126) Elo CCRL 40/4 and 2644 (+152) Elo CCRL 40/40 as of writing
- New selection of compiles.
- ``New'' is for BMI2 capable processors and newer. Also assumes support for AVX and FMA instructions.
- ``Old'' assumes support for SSE4.2 which was released over a decade ago by now and should give a solid speed boost over the last compile (10-15% or so)
- ``Ancient'' assumes only support for 64 bit and whatever gcc assumes for Ofast, should work for most everyone =).
- Somebody asked for an Android compile on github. I intend to try to do this, but this may take a while as I am busy irl and have never done this before.
- Reuploaded Winter 0.2 without the accidental .git folder. Also uploaded a minimalist version which should work. I haven't tested this, but I am quite certain they should both be working... Thank you Gabor Szots for the feedback!
- Simple endgames are now recognized as draws. This will not have an effect in CCRL due to tablebase adjudications and I dont expect it to have a real effect on Elo without adjudication. It is mostly quality of life in analysis and it feels better for Winter to understand certain endings faster in HGM tournament =)
- Eval function improvements:
- Passed pawns are more accurately evaluated as Winter differentiates between pawns the opposing king could stop if the board were empty and those it couldnt
- Bishop position (as a PST) relative to the opposing king is now evaluated on top of previous metrics. I tested this with each minor and major piece individually and felt only bishop was worth it, but it gave me like 20 Elo, so I could recommend trying this. Shoutout to Michael Sherwin who tested this in Romi and got me interested in the idea
- Search function improvements
- More aggressive depth dependent null move reductions
- Greatly simplified static null move pruning. My previous margin was a complicated function based on some statistics I had measured. While the formula may have been correct at the time, I think I was overfitting to the engine as it was. The new formula is a simple depth * score margin.
- Revisited late move reductions. I spent quite some time generating and looking at statistics and I have some ideas with respect to how the scaling should look dependent on move index and depth. So far I accidentally reinvented SFs LMR formula. I believe some terms might be missing, I tried one of them, but at least with my guess for a value it ended up worse than the SF formula.
- Started with some desperately needed refactorizations, I separated my gradient descent code into a new source file. This might make it more useful for someone interested in borrowing some code =)
- Fixed a bug which would make Winter play terrible moves if it was run via Lichess Bot API. Thanks again to Lichess for creating the API!
- As mentioned above, Android release
- Change search so it doesn't recognize 2-fold repetition as a draw. So far it has always felt wrong, but only evaluating 3-fold repetitions as draws has cost Elo. I intend to go in depth here and see if I can avoid losing Elo somehow. Will probably take a look at what SF does, as it seems to currently enjoy repeating, and the SF team wouldnt allow that if it cost them Elo =P
- Chess960 support
- I think its a cool thing to support, however I believe it can have good side effects if you can train on data from chess960 as your eval function may overfit less. Even if this may cost Elo, it should help make it easier to improve the eval function.
- Sidenote: Leela should support this. I might add this to Leela myself after adding it to Winter. Even if they don't end up training with this, I imagine some people would enjoy the option.
- OpenBench support. Raoni Campos mentioned this to me. If you haven't already, take a look at Andrew Grant's awesome contribution here
