This version got many bug fixes, two of them in threefold repetition and 50 move rule.

21 evaluation parameters were automatically tuned instead of 12.

Added parameters in eval: rook pawn penalty, isolated pawns, blocked pawns, bad bishop and opposite colored bishops.

The strength is probably above 2180 now.

Hi Werner,

great news!


But i think, y missed one bug (i see this also happening in v0.36) - as far i tested.

this only happening, when i give "searchmoves".
Can y take a look?

If you change the name of the binary expected in the code from galjoen_eng to galjoen_eng.exe then the interface works fine when built with Mingw on Windows also.

After make install, I start it like this:
dcorbit@dcorbit MINGW64 /usr/local/games
$ ./galjoengui.exe

Yes, I'll fix this asap.

Excellent!
I will try to make galjoengui aware of both 'galjoen_eng' and 'galjoen.exe ' (I don't like galjoen_eng.exe on Linux).

Perhaps something like this:

@Juergen: the searchmoves problem should be fixed in this new version.

@Dann: the interface checks its own name now. galjoengui will load galjoen_eng and galjoengui.exe will load galjoen_eng.exe

Hi Werner,

yep, works. Thanks.
I'll update galjoen on my next picochess release then.

That is a very clever solution.
