cutechess-cli 0.8.0 released

[ilari]

Greetings,

On my 64-bit windows 7, after running cutechess-cli.exe, I get msvcp140.dll missing. Maybe according to internet, you should statically link this project.

As Gabor said, msvcp140.dll is included in the package, but only since I updated it about a day after release. So you may have to download again.

This time api-ms-win-crt-runtime-l1-1-0.dll is missing.

Looks like you'll need the Visual C++ 2015 runtime: https://www.microsoft.com/en-us/downloa ... x?id=48145

You can also install it via Windows Update.

This means that for some reason g++ tries to compile in C++0x mode when it should use C++11 mode. Did you try the build with "qmake && make" commands?

[flok]

In fact that is exact what I did!

Sorry, I didn't look closely enough. It looks like you're trying to compile against qt 4. CuteChess requires at least qt 5.3.

Thanks for the update.

There's a new "-seeds n" parameter which sets the first n players as seeds in the tournament. The top two seeds can't face each other before the final, top 4 before the semifinals and so on. And if the total number of players in the tournament is not a power of 2, seeded players are prioritized to receive a BYE (ie. go straight to round 2).

Unseeded players are positioned randomly. By default all players are unseeded.

Do 0.8.0 support two computer match do benefit from ponder?

Can you please rephrase your question? Pondering is supported for all tournament types regardless of the number of players.

Hi Ilari,

thank you very much for the new release!

I tested it and possibly found a bug: Engines don't switch the sides any more if you set up a tournament with >2 participants.

Example 1: cutechess-cli.exe -tournament gauntlet -engine conf="Komodo" -engine conf="Gull" -engine conf="Stockfish" -each tc=5+0.05 -rounds 10
This command leads to Komodo only playing white in all games against both opponents.

Example 2: cutechess-cli.exe -tournament gauntlet -engine conf="Komodo" -engine conf="Gull" -each tc=5+0.05 -rounds 10
There are only 2 participants left - now everything works like it should: Sides are switched after each game, so Komodo plays 5 games with white and 5 games with black.

This error didn't appear in version 0.7.3 which was the last version I tested.

Best regards
Timo
