New Version of Maverick Released!

Post by Steve Maughan » Sun Sep 15, 2013 11:35 pm

Maverick is steadily gaining strength so here's the latest version - Maverick 0.5; the first version I regard as reasonably strong:

http://www.chessprogramming.net/compute ... -released/

I'd estimate this version to be about 200+ ELO better than the previous version.
  • Added more basic endgame knowledge
  • Added passed pawn evaluation (I think this added a lot of strength)
  • Beefed up the evaluation routine to include basic terms such as mobility
  • Fixed a nasty hash bug to do with mating positions
  • Added one-reply to check extensions in the first ply of the quiescent search (help with some tactics – little impact on playing strength)
  • Enabled hash cutoffs at PV nodes
  • Nodes per second have dropped considerably due to the slower evaluation (now between 3 million and 5 million on my 2.8 GHz i7 notebook)
  • A bazillion tweaks
Please let me know if you have any test results for Maverick or if you find a bug!

Steve
