Re: Syzygy DTZ data explaination?

I guess you want to rank the moves strictly by their dtz values. Almost! My purpose is to explain for a given endgame why this move should be made but not others. I lost when following your code for a while. Do you get information to rank all moves at once (query one) or do you make-query one by on...

Re: Syzygy DTZ data explaination?

I guess you want to rank the moves strictly by their dtz values. This is what I do here https://github.com/joergoster/Stockfish/commit/56d5abea0a87f66efae2f5bf93376f3181ef95fb in a stockfish branch to build a mating sequence. This is what I get with your position: position fen K7/8/2R5/8/8/8/8/7k w ...

Re: New Tool for Tuning with Skopt

After trying this script a little on some search parameter I am not in success. Any advice will be welcome about choosing the good script configuration and a reasonable number of games. For now, 1000 games to tune 4 or 5 parameters at a time seems not good. People have had some problems with skopt ...

Re: New Tool for Tuning with Skopt

It's a nice project, but i had issues: - ahash from log file should not consider number of games and even concurrency, that way would be easy to run a 200 game session run using 100 games from previous run. - Let me use options that are not seen as UCI options, i don't wanna to expose all possible ...

Re: New Tool for Tuning with Skopt

Tried to monitor memory and cpu usage of tune.py. I tuned 6 eval parameters, concurrency is 6 and set at 1000 games and 50ms/move, others are default. Started monitoring after 100 games, and after around 520/1000 games I stopped the tuner. Memory usage increases as games increases. CPU usage also i...

Re: New Tool for Tuning with Skopt

Jorg, have you tried one of the other base estimators supported by skopt/tune? They might be faster. You can "RF", "ET" or "GBRT". I'll think of other ways to speed up for many games. Maybe something like running more than 2 games for every choice of parameters. But even inverting a 2000x2000 matri...
