Re: Sloppy 0.2.0 released

About bitbases: also Toga and bright are worse in EET suite with full 5 piece set and better with 3-4 set. Any good explanations?? Jouni I think the worse rating in general would be because 5-men egbbs take so much time to probe, or perhaps there are bugs in the egbb library. But if the EET suite r...

Re: Sloppy 0.2.0 released

Thanks for compilation work, Jim! So you finally added bitbase support. We'll just have to edit the egbb path on the config file in case we enable usage, as configuration sets path to "bitbases" folder (within the engine location). Am I right? Correct. And the library (.dll or .so) must be in the bi...

Sloppy 0.2.0 released

Downloads and more info here: http://koti.mbnet.fi/~ilaripih/sloppy/ As it says on the site, I'm making (and already made) some pretty big changes to Sloppy, so I wanted to get one more stable and fully functional version out before things get messy. Sloppy 0.2.0 is that release. I call it a small u...

Re: Benefit of tablebases (probably old news)

I have mixed feelings about tablebases/bitbases as well. Recently I added support for Scorpio's bitbases to Sloppy, and after about a thousand games (I run 100-game contests) I'm still not sure how much they help because of the great variation in results. Against Slowchess Blitz the average score we...

Re: shame on toga authors

Sad day for computerchess. You could argue that it's a sad day for computer chess as a competitive sport, but it's definitely a happy day for computer science. And that's what computer chess is to me. Actually, in my opinion it's not bad for the sport either because derivatives aren't usually allow...

Re: Sloppy Manners (Sloppy prevails)

Thanks guys! I should have plenty of time to code during my holiday so who knows, maybe I'll even get Sloppy's parallel search finished.

Re: Sloppy Manners (Sloppy prevails)

Cool. Thanks for running the tournament.

The next version of Sloppy is on the way, I'll probably do a release before next year. It's already about 100 ELO stronger than v0.1.1.

Re: More on legal move generation

Another idea is a move generator that also determines if a move gives check. This can be done while adding only a few percent to the movegen time. This is exactly what I've done in Sloppy. I use the information mainly for move ordering, extensions and reductions. Doing this takes about 7% of cpu ti...

Re: Creation of Opening books -- free to the community

I thought about this a bit more, and I don't understand why it would be a problem to add the binary books to the repositories, assuming that the books really are free. Gnuchess-book and Crafty's books are already there. These are data packages, not programs, so it shouldn't be a problem that they're...
