- 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 tunable constants as options. I just need to define them using tool input options.
- Can't make it work with more than 100 games, tested with 6 options.

I have pushed a new version that should fix these issues. Thank you for the suggestions!

It turns out that skopt saves all previously "fitted models" for the gaussian optimization. I now delete all but the latest, which will hopefully mitigate Joerg Oster's memory leak problem.

Very nice tool! Thx a lot for sharing it.

jorose,

How many games did you have to run during tunning to get this elo? I am trying to tune SEE evals in Igel, not clear yet how many games I need to run. Also, I presume for search it is better to use nodes limit per move I assume?

Thanks!

I'm trying it now, using xboard protocol, and I'm not really successful because python-chess seems to be rejecting "usermove=1".
Anyone experience this before ?

Soon I'll be trying it with Myrddin, also an xboard engine. Hoping you have some success!
