Re: Re-Pair compression questions

For the same reason i have some doubt that replacing Huffman with any of the ANS entropy encoders is a good idea. It would make the tables a bit smaller, but that is just one part of the story. (For DTZ tables probed only at the root it likely does make a lot of sense.) I think it's worth to try us...

Advance chess

Wikipedia suggests that chess engines are now stronger than centaur (human + engine) players (https://en.wikipedia.org/wiki/Advanced_Chess#cite_note-7). "Computer chess engine Zor won the freestyle 2017 Ultimate Challenge tournament. The best human plus computer came in 3rd place. In 2017, chess com...

Re: Feed bayeselo with pure game results without PGN

Thank you! I'm going to make a tool to feed results in a most compact form, for example: engine1: {engine2: {w: {100/100/101}, b: {95/100/105}}, engine3: {w: 101/100/100, b: {96:100:104}} engine2: ... etc So instead of multiple games or game headers you will have just results. In the case you're hav...

Re: Feed bayeselo with pure game results without PGN

Thank you! But I have a multiple versions, so I need to fit their ratings. My framework is based on genetical approach. The previous version was based on playing vs base version, but there are two problems: 1) if you will be able to use games of some sibligngs vs each other it will help you to save ...

Re: Feed bayeselo with pure game results without PGN

Why not feed it a minimal PGN file with the players and the result ? cutechess-cli should be able to produce minimal PGN. Because it's too slow to parse PGN with 10 mln games, even minimal, especially when you need to do it after every batch of games per CPU core. Moreover, it's hard to even store ...

Feed bayeselo with pure game results without PGN

Hello all! Do you have any ideas how to quickly feed bayeselo with game results array? In my tuning framework I'm going to play several millions of games per day, so storing them in PGN and then feeding them to elostat will be too slow. Of course, it's possible to tweak elostat source to do it, but ...

Re: SmarThink 1.98 is out

May be it's because of some hashtable data from previous search? I've tried to compare on your position and it still looks the same: Transposition size is 524288 entries (13631488 bytes) Pawn hash size is 262144 entries (8912896 bytes) Aggressivity = 100 (50)% Cowardice = 100...

I will use the standalone AVX2 version for my tests;
although the other AVX2 version shows a bit different output lines and kns.
I've just tried every of executable and nodes count is exactly the same for the same depth. NPS of course differs because AVX2 is the fastest compile.

I've updated smt198.zip — UCI version is fixed, also includes AVX and _standalone versions.
