I've just released the source code for Beowulf version v1.5 on my website (see below). I never really got round to releasing v1.4 properly, though I believe Dann did release the .exe at some point. New since version .1.3; Version 1.4 Bugfix to opening book code Bugfix to hash table code Incremental hash key updates (Which had virtually no effect for those of you who said it would!) Rewrote NULL move depth reduction code Fixed problems with the analysis mode Tidied up one or two bits of code Version 1.5 Eval score tweaks Fixed one annoying bug in the scoring function Personality files - customise the computer player! A few slight algorithm changes I hope it works OK. I fixed several bugs that I'd introduced and improved some compatibility problems. The personality files are a big new addition - check out the beowulf.cfg file where you can specify the path to the personality file of your choice (or none at all, where Beowulf decides on sensible defaults). Thanks to Dann who did most of the coding for this one. I think the overall strength is slightly higher than version v1.3. I played a match versus Sjeng v10.0 overnight on 5 min blitz and Beowulf won 41-22. Enjoy! Cheers, Colin Beowulf Website: http://www.ast.cam.ac.uk/~cmf/chess/beowulf.html
