Garbochess v2.10 released

Post by gladius » Thu Mar 27, 2008 1:46 am

You can grab it here http://forwardcoding.com/projects/garbo ... s-v210.zip. In my private testing, it is roughly 75 ELO stronger than v2.02.

Thanks to everyone who reported bugs in the previous version! Hopefully they should all be fixed now.

New in this version:
- 1.5 ply LMR for really bad moves
- Better search ordering above 5 ply
- Changed king shelter penalties, now more dependent on pawns directly in front of king
- Better ordering of root searching
- Better time management (extend search on fail low)
- Fixes some instant moving bugs
- Fewer checks generated in q-search
- Increased mobility values
- Adjusted pawn evaluation

+75 against the previous version, which is 2534 on CCRL. Mind you, there are very few games there, so 2.02 could be quite a bit weaker/stronger then that.

In fact GarboChess2 has played only 10 games for the CCRL 40/40 list. The errror margin for that 2534 value is +225/-178 so more or less meaningless at the moment.

On the CCRL 40/4 list there are 'already' 24 GarboChess games, its rating there is 2717 +127/-122.
