configure engine : unclear settings

tissatussa commented 3 years ago

when adjusting the settings in CuteChess, i see 5 entries and some are unclear :

Ownbook : on your GitHub page(s) i see no opening book file .. how should this option be used ?
SyzygyPath : originally this was "[..]/v2.3/./data/egtb" and i changed it to "[..]/v2.3/data/egtb" which is the same and also works ..
Opening Mode : 3 choices but it's unclear what they mean .. and does this apply to the Ownbook checkbox ? Note: there's a typo with 2 'nn' ..

Hi, I have added text to the readme file: https://github.com/bagaturchess/Bagatur/blob/master/README.md Please let me know if something is missing? For now I cannot fix the typo with double 'n', because some people may use this option. I have to think about it how to not surprise people negatively by changing the option name ... Bets regards, Krasimir

Please let me know if something is missing?

_SyzygyPath (type string default \arena3.5.1\Engines\BagaturEngine.2.3.\data\egtb): path to the syzygy tables.

The default path differs on my PC : in CuteChess, when i click "Restore defaults", it shows [..]/data/egtb Note: my working directory is "[..]/bin" I think the prefix "\arena_3.5.1\Engines\BagaturEngine.2.3." is confusing, because users (like me) may have another install path.

You also could explain that these End Game TableBases are a subset, not the full 7-men pack, which can be (freely) downloaded at many places on the internet.

For now I cannot fix the typo with double 'n' ..

OK, it's a minor detail :-)

Rest is clear, thanks.

Hi,

I have corrected the text. Actually the directory is set to ./data/egtb and its prefix (like \arena_3.5.1\Engines\BagaturEngine.2.3) is added later depending on the path from where you start Bagatur - the working dir. This should work when you start Bagatur with its exe files but will not work when you start it via bat or sh files. So in your case it has to be set.

Best regards, Krasimir

Yes, i think the text of the chapter "Syzygy Endgame Tablebases" is now complete and clear. The path to the egtb folder is also clear, here's my launch of Bagatur :

~/Apps/ChessEngines/Bagatur/v2.3/bin$ sh ./Bagatur_1core.sh

it's a little strange : "[..]/v2.3/./data/egtb" contains a "/./" which could just be "/" . The total path string can even be "../data/egtb" without any prefix, am i right ? So, go to the parent folder and then into 'data', because 'bin' is the working dir. Nevermind, your path works ..

Yes, it works the same way on my setup! :-) This has to be fixed. When bat and sh files are used, the default directory for SyzygyPath is wrong. It should first go one level up in the directory structure and then set it to ./data/egtb. The dot symbol is also redundant here ... it will work with '/data/egtb' as well. Best regards, Krasimir P.S. I have updated readme.md again. Anything else still missing?

tissatussa commented 3 years ago

I think it's OK now : the README is clear and complete, and you are aware of some shortcomings -- to be solved .. good luck !

bagaturchess commented 3 years ago

Thanks for your collaboration!

Let's keep this issue for a while in order to remind me that I have to update the readme.md once the online syzygy starts working. :-)

Best regards, Krasimir
