Arasan 19.0 + updated test suite

[Krzysztof Grzelak]

Excuse me just get an option TBHits. Previously, she did not want to work during the analysis. One interesting thing I noticed during the analysis at Arasan 19.0 in the Arena. If you select an option in the Arena - Common max.CPU cores setting - 4 it immediately in the analysis do not show up Tablebases. If the option Common max.CPU cores setting - 1 immediately show Tablebases. Although I have processor i7.

I noticed that as the Arena, enter 1 is at once the analysis is written 0 TBHits.
I would add to those what they will do in the Arena - any change options Common max.CPU cores setting - please close the program and restart it.
I'm going back to the program ChessGUI.

I have gotten it to work in Arena in UCI mode. There were a couple of UCI related problems that I needed to fix. I will get out a patch release with these after some more testing.

Arena 3.0 for Winboard compatible engines appears to work for Gaviota tablebases but I don't think it supports other tb types.

Hi Jon,
thanks for the update. No problems here with v. 19.0.1.

What means syzygy probe depth = 4?

Do I have to change it to 5 if I have e.g. 5men installed?

best wishes
Werner

SyzygyProbeDepth is the minimum depth in search at which it will probe the tablebases (except that it always probes in the top two plies).

So if you set it to zero it will probe at all non-qsearch nodes. If you set it to 4, it stops probing at depth 4, so will stop probing before the qsearch.

I don't know what the optimal value is. It probably depends on your hardware. If you have SSD for example you can probe more.

YES !

Hi Jon.

Thank you for the new versions. I decided to test the new version of the program ChessGUI and Shredder Classic 4.I have to admit that both programs work tablebase syzygy. Testing program ChessGUI occurred to me a few questions.

1. Is the file arasan. rc is needed for a program Arasan 19.0.1

2. If I change the file arasan.rc entry for search.syzygy_path=D:\Syzygy\dtz3456;D:\Syzygy\wdl3456 this program Arasan 19.0.1 does not see it.




3. I noticed it in the program ChessGUI



As you can see both files they can not see each other.

4. Even after the programe ChessGUI and the engine Arasan 19.0.1 - SyzygyTbPath D:\Syzygy\dtz3456;D:\Syzygy\wdl3456 program strangely shows that only showed that he uses tablebase syzygy.



And should show in SyzygyTbPath type string default.

You should be able to run arasan without the .rc file. If it isn't there it will just use some internal defaults. Also currently the GUI always wins: if the GUI sends tablebase option commands they override what is in the .rc file or set internally. And some GUIs do have their own preferred defaults.

I don't know why it isn't updating the UCI default value from the .rc file. I can look into that.

YES !

Nope ! I'm in error here ! 5 for 5men installed it's for"Probe Limit" !!! Sorry !

What kind of error you are writing and under what GUI. I did a test program ChessGUI with syzygy probe depth =6. The program does not show any error.
