cutechess-cli 0.7.0

[ilari]

Not related to the GUI...but I got a quick question regarding random opening.

If we have concurrency > 1, do the processes share the same seed?


Thanks in advance.

Cutechess-cli runs in a single process. It uses threads which all share the same random seed. Randomization (indexing) of the openings is done before the match even begins. This guarantees that cutechess-cli doesn't pick the same opening twice until all openings have been played at least once.

Hi Ilari,

Have you seen this

http://talkchess.com/forum/viewtopic.php?t=57465 ?

I have run some simulations and the posted code really works. Perhaps you are interested in simplifying the SPRT implementation in cutechess-cli?

Another advantage is that this is a clean implementation of a standard algorithm (the GSPRT) with proven properties.

Thanks. I actually managed to reproduce a similar problem but without warning messages: when I used really fast games, at some point the PGN output would just stop. This on Windows 10 with an SSD HD. I just pushed a commit that fixes this problem and makes PGN output more efficient: https://github.com/cutechess/cutechess/ ... a87ed18d1a

Could you try fetching the latest code (which includes the above commit), compile and see if you can still reproduce the "Can't write to PGN file" error? You'll have to recompile the whole project (lib + cli).

Hello.
First, thanks for this great tool. The latest Windows executable does not contain the fix, or does it ?
Well, is someone able to provide a new compile because the version i am using is still not writing all pgn games to the file.
I really would like to upgrade my old but stable version 0.5.1 (with version 0.6 i did not have any luck too)
Thank you in advance.

I could share my compile, but not today, my internet connection is not good.
I am also waiting for the official fix in FEN header tag value where hmvc and fmvn are missing in the output pgn when start position is from epd file. Also the possibility to write the termination header tag in every pgn, be it as draw by 3-fold repetition, white mates, draw by insufficient material and others, time forfeit is already there.

Now the latest Windows executable does contain the fix. It's just not official yet because we haven't updated all the other binaries. But feel free to download cutechess-cli 0.7.1 here: http://koti.mbnet.fi/~ilaripih/bin/cute ... -win32.zip

Just uploaded my win 32 compile of version 0.7.1, because in your site it was still 0.7.0, under "Installing". I have not uploaded the dll files though.

Good morning,

thx a lot, Ilari + Ferdy, for the new version.
