Aart's Blog

November last year, I posted a blog entry on my progress with "Deep" BikJump, i.e. adding multi-threading to my engine to speedup the search. Due to many distractions, I have not worked on that feature since that posting.... The chess engine bug is starting to itch again, however, so I decided to pick this up. Hopefully I can release a SMP version of BikJump soon!

Leo Dijksman kindly posted a chess engine rating list on the WBEC-Ridderkerk forum , based on edition 11 to 16 of the WBEC-Ridderkerk computer chess competition. Below I show some stats for various versions of BikJump. Rank Version Elo + - games score oppo. draws 517 BikJump 2.01-x64 2111 105 105 30 50% 2109 27% 609 BikJump 1.8-x64 1995 132 125 30 70% 1798 20% 662 BikJump 1.1 1911 141 160 26 23% 2199 8% 693 BikJump 1.5 1851 131 131 25 50% 1823 12% Many thanks to Leo for providing the ongoing WBEC tournaments!
