I released Cheese 2.1 :

http://cheesechess.free.fr/en/download.html

This is a bug fix version, maybe few ELO improvement.

Code: Select all

- fix initialization of UCI Strength in .ini file
- fix FEN parsing with FRC castling rights
- fix few problems with threads
- rewrite UCI & Xboard protocols code
- small optimizations and simplifications
- fix a problem with LMP
- increase LMR for non PV nodes

It does not follow movetime command.
This is on UCI_elo 1500.

Examples.
Almost 3 sec from 1 sec.

It does not follow movetime command.
This is on UCI_elo 1500.
I was not able to answer before, (holidays and no internet connexion).

This problem happens only when using UCI_ELO ?
Are you using Windows or Linux version ?

Thanks.

I try your examples and other potions and I can't reproduce the problem.

Can you tell me if you can reproduce this problem every time, and if it only appear in Cheese version 2.1 ?

In my code I increase a number at the begining of the search function, and I test search time when
the counter is > 30000, UCI Elo use only Sleep of 20 ms (every X nodes), I don't understand what is wrong.

I run Cheese 2.1 from my script that uses python-chess module, analyzing 5k positions, the log I showed is from it. I was curious at that time why other engines were already finished but Chesse was still analyzing.

go movetime seems problematic (madchess too, other engines are OK), probably python-chess is also part of the problem. Just ignore this report if you cannot reproduce it.

I am now using go wtime btime ... currently for Cheese. Time spent is not perfect but is enough for my needs.

Thanks, I will try with your script to see if I can reproduce it when I have some time.
