Post by Codesquid » Wed Jun 19, 2013 10:01 pm

Hi all,

a new version of Octochess has been released.

This versions adds support for Multi-PV analysis mode. In addition, moves can now be excluded from analysis.
There have been some bug fixes as well, mostly regarding endgame evaluation and subtle problems with enpassant captures.
Last but not least, some modifications have been made to the time keeping, this should solve issues with timeouts a few users have reported.

As always, you can download the latest version from http://octochess.org/

Please let me know if you are having any issues with the new version.


The complete list of changes:
  • Implemented Multi-PV analysis
  • In analysis mode, the moves to be searched can be specified
  • CECP: hint command is now supported, it returns best move from transposition table.
  • More accurate timekeeping
  • Handle KRPvKR endgame
  • Improve KPvK endgame
  • Adjust scores if stronger side is pawnless
  • Smaller book format
  • Fix handling of enpassant in hypothetical positions not reachable in a game from the start position
  • Fix scaling of scores in opposite-bishop endings
  • Fixed overflow in evaluation of king attack
  • Various code cleanup
  • Faster statistics calculation

Thanks, Tim. Lots of fixes and probably a lot of work, too - I will give it a test :)
