Re: BONA_PIECE_ZERO

I'm not sure why groups like TCEC are okay with calling Stockfish's implementation a "library" for "everyone to use". Do your own work, and it will pay dividends down the line. You also skip all the trash thats in Stockfish because its a weak Shogi port that was never cleaned up. I guess that they ...

Re: Official Release of OliThink 5.7.5 including a Java-GUI

Beyond Glaurung strength is mind boggling. I am really stunned at the progress of Olithink. I think you are teaching everyone a powerful lesson about simplicity (and even beauty). I guess that one of the things the NN engines add that is not properly performed in most chess engines is the focus on m...

Re: EGTB compression

I see. Yes, I meant LZ4. With the HC version using -9, it gets very good compression ratio. Now, it compresses slowly using those settings but it decompresses ultra-fast. That is why I thought it would be a good compression algorithm for tablebase files. Even though compression is slow, you only hav...

Fixing the LC0 imbalance defect

Suppose that LC0 were trained not from self-play games but from data extracted from its games on TCEC, CCRL, and CEGT?
Since those contests include lots of arbitrary openings, many of which are imbalanced, I wonder if it would help the problem.

Re: Why does TCEC use unbalanced opening?

TCEC won't change the imbalance book and here is why: They are using the contests to generate money. If the contests go 3 wins SF, 0 wins LC0, 97 draws they will lose followers. And what about controversy? (E.g. us debating it right now)? Controversy is another form of advertizement. Good for busine...

Glanced at the standing:

Sf destroys Leela 9:1 =36 pairs. Poor Leela.
Soon to be 10:1.
Of course the error bar is huge, but that would be 60 Elo higher.
That is quite a bit higher than the 12 Elo difference they have listed at tcec
