It's the second version of my open source chess engine. Unlike the first version Sloppy 0.1.1 compiles also with Microsoft's compiler (makefile included). Configuration (hash size, etc.) is now also easier because there's a config file.
As for playing strength, this version should definitely be stronger by 0 - 100 ELO, thanks to improvements in search and a complete rewrite of king-attack evaluation. I haven't run enough test games to be absolutely sure though.
As always, I'd very much appreciate faster binaries, feedback, and especially a binary for Windows x86-64.
Regards,
Ilari

Re: Sloppy 0.1.1 released
I was waiting for the release of this version. Let's hope I have found a new comer that can out do bugchess.

I wish I had a logo to go with it.

Re: Sloppy 0.1.1 released
Thanks! I've uploaded the binary to my site.Sloppy 0.1.1 win32 Intel compiler 10 pgo build
I just ran 100 bullet games against BugChess2 V1.5.2. Sloppy 0.1.1 (64-bit) got 55% of the score (41-31-28). Being a bitboard engine, the 32-bit version would of course be a bit weaker.I was waiting for the release of this version. Let's hope I have found a new comer that can out do bugchess.
Nicely done. Logos seem to be important in the computer chess world.You can find my Sloppy logo here ...

You arent kidding, my Alfil program gained about 30 points because I used a Graham Banks logo.ilari wrote:Nicely done. Logos seem to be important in the computer chess world.
Re: Sloppy 0.1.1 released
At my time controls, sloppy is still lagging behind Bugchess after around 80 games. May be my time control (1m+1sec) is too fast for sloppy, and simple tricks like the ones Uri recently did, printing the pv etc, could help it a lot.SzG wrote:Ended 14-6-12.

Re: Sloppy 0.1.1 released
It's very likely. I haven't done proper testing with the "whole game in X minutes" time control. The time Sloppy allocates for each move is roughly "(time_left / 30) + extra_time". It's probably a good idea to replace "30" with a significantly bigger value. It's line 848 of search.c, in case someone wants to experiment. I sure do.Tony Thomas wrote:At my time controls, sloppy is still lagging behind Bugchess after around 80 games. May be my time control (1m+1sec) is too fast for sloppy...
Can you elaborate, how could printing the pv help?and simple tricks like the ones Uri recently did, printing the pv etc, could help it a lot.

I've compiled a 64-bit GCC-Mingw64 version >

This is untested - I don't have a 64-bit Windows environment to test, so don't complain if it doesn't work
