Re: stockfish 10 vs. Mephisto III S Glasgow

This is really not AI but instead artificial stupidity. The progress you've made in about 8 months in this thread disproves the existence of HI. My part on this posting is mainly to quote the source: https://glarean-magazin.ch/2019/04/18/kuenstliche-schach-intelligenz-leela-chess-zero-projekt-lc0-c...

Re: Include 4men syzygy in an engine

With this changes the probing code gives wrong results, what have I missed? Are there other parts of code to change? Do you have a version of your program that works without the changes you made (so that mmaps() the files into memory when needed)? If you do, then it should be relatively easy to fin...

Re: Sysygy Shatranj?

Would it be trivial to adapt the Syzygy EGT generator for Shatranj? Or would it be easier to just write a dedicated generator for that? I am only interested in the WDL statistics of a few specific 6-men end-games (KRFE-KR and KFF-KFE). I don't need the tables itself, so I don't care about compressi...

Re: longest 6-man EGTB win

Anyone have a list of positions of the longest 6-man EGTB wins that meet 50 move rule requirements? I.E. no cursed wins allowed I think to do this accurately, you must have the complete Lomonosov files. They have distance to mate. But they don't take into account the 50-move rule. Whenever they sho...

Re: Another take on DTS?

Hello everyone, I am surprised to see currently so few interests in Dynamic Tree Splitting in comparison with Lazy SMP. Is it because DTS seems to be adapted to multiprocessors or large-scale network while Lazy SMP is for multithreading? Is there any scientific or empirical comparison between the t...

Re: Syzygy DTZ data explaination?

Can you help me confirm what I have just guessed for the above case (position K7/8/8/8/8/2R5/8/7k b - - 0 1) 1) All raw data DTZ of all three black-King moves (Kg1, Kg2, Kh2) has the same rank -1000 (losses with little chance to reach the 50-move rule) Your position has three moves, all losing with...

Re: Syzygy DTZ data explaination?

The problem has not been solved yet as I thought: Indicating repetition to Fathon code does not always give me enough information. I don't know what Fathom does, but in Stockfish ranks work as follows (it may be the same for Fathom). If the current position is in the TBs, each move is assigned a ra...

Online Syzygy is a mess. It's crap. Not the shortest way to mate. In your pgn 11.Nb1? is -8# (11...g3 8#) , best is 11.Kb2 -12# (6 men Nalimov), your 12.Nd2 (-6#) lost another move, best: 12.Kb2 -7# (12...g2 7#) 13.Nb1? best is 13.Kb1 After 13.Nb1 is g1Q mate in 4 , not your 13...h4 ( mate in 7 ) I...
