Re: Would More Complex Classic Evals Improve NNUE Nets?

As we all know, the classic evaluation functions are a tradeoff between speed and accuracy but given that most NNUE nets are trained using fixed depth search results, speed would no longer be a factor. I was wondering if much more complex/accurate evaluation functions would result in stronger nets....

If anyone is looking for a source of binpacks, I've been building and releasing them on one of my sites for download.

https://openchessdb.com/nnue.html

Just added 6.5 Billion more positions.
What is a binpack, exactly?
A format for training and validation files.

Re: Any good way to broadcast tournaments?

I mainly use cutechess-cli for running tournaments. And I sure will love to see the progress from time to time even when I am not home. I was thinking maybe there is a way to broadcast ongoing tournaments. I thought about pgn2web, but unfortunately cutechess-cli only writes the PGN after the game i...

Re: nnue-trainer

I am aware of the random move options. Actually as I have posted before, the way gensfen does this seems to me unsound, because it will score the whole game with the ultimate result, even though a random move inserted in the middle can change the eval significantly, and so really then the previous ...

Re: King safety evaluation

Hi. During the last couple of days I've been struggling with writing a working king safety evaluation. Every time I try to test it against the oldest version of my engine it seems to either loose 30-60 elo or only gain a negligible 5-10 elo (as compared to the results of others's implementations th...
