DownloadSince a little bit more than a year and a half, I've been working on a C++ "rewrite" of Prédateur. So this latest pascal version of my engine might well also be the last one, as the C++ version is getting mature and closer to delivery. This 2.2 version is most of all a speedup/bugfix release. Testers will tell, but I think the Elo boost might be bewteen +50/+100 compared with Prédateur 2.1.
The archives includes binaries for :
- win 32
- win 64
- Mac Intel
- MorphOS PPC
Here's what have changed:
A lot of speedup everywhere, made possible by using Intruments, XCode's code profiling tool.
The promotion "bug" is fixed, so Olivier and Leo should be happy, now ;)
Many ply-variables have been gathered into fieldbits, speeding up many parts of the engine.
The search have been polished and finely tuned.
Prédateur now understands the "go nodes xx" command.
Time management and response improved (Prédateur can now play games will less than 200ms per move).
perft is now available to everyone.
More binaries in the archive: MorphOS PPC added.
Many tidbits here and there I don't even remember.
