Which executable do you use?

Re: SmarThink 1.40 updated

Thanks, Sergei. Can you, please, link with static libraries ? ... so that we don't have to go downloading virus-infected dll files from internet. Matthias. I hope this dll is in redistributable package, so you can download it from Intel site. As I've understood Intel compiler XE 2013 has some probl...

Re: SmarThink 1.40

Thanks, SmarThink has always been an interesting chess engine. Is there any chance you could compile a version for MacOS or Linux? Thank you. It's possible if someone will help me, because I'm not familar with these platforms. But at the moment I hope I will be able to make MP-version — this is my ...

Re: Probabilistic approach to optimize search tree

When we're using alpha/beta family, in best case we can reduce a nodes count to square root of the same count of the exhaustive search tree. Practical spoken this is wrong. Though theoretical spoken, professor Bob has an argument there. The proof doesn't take into account hashtables for example. At...

Re: Probabilistic approach to optimize search tree

Please feel free to correct me if I'm wrong. You are right. Difficult doesn't mean impossible :) When we're using history pruning/reducing, our descision to cut-off is based on history value. In Rybka and it's clones it works like "if eval + history_score < alpha → cutoff". In my SmarThink at...

Re: Probabilistic approach to optimize search tree

Can you explain what you mean by "a cutoff changes the best move at root", "a cutoff affects PV", and "a cutoff results in nothing"? Which kind of cutoffs are you thinking of - most probably not the usual "beta cutoffs"? In my view, performing a cutoff *never* changes the best move at root or the P...

Re: Probabilistic approach to optimize search tree

I don't think that this is so simple... The problem is that some cutoffs are much more valuable than others. * The only really valuable cutoffs are those which change bestmove at root. * Also valuable are those which affect PV and by doing that affect the evaluation of the best move. * Most cutoffs...
