why I say FR? It will eventually replace ID cards, credit cards etc.
I hope I'd live long enough to see Olympics played electronically. :D

It is very questionable whether the best engine developers (programmers and book builders) aren't all at WCCC anyway.
And maybe in a few years from now, having people to know there is such a thing would be an achievement.

Re: Database snapshot

Thanks for making the nice web interface, and thanks to noobpwnftw for building the database. Agreed. Who is to say that minmax is better than this scoring, ... Not sure what "better" might mean, but minimax scoring at least has the comforting (to me) property that scores remain constant along any ...

Re: Database snapshot

I do not understand why multipv=4 and depth 22 is the best. For multi-pv I think that it is dependent on the position and for example it is not logical to have multipv=4 in positions when there are only 2 options that do not lose a lot of material when it is logical to use more than 4 options in ca...

Re: Database snapshot

One principle has to be noted that the score of a move provided only makes sense to those of the moves on the very same position. The database handles aggregation of scores on subsequent lines internally and it does not follow mini-max calculation. But two distinct positions, say B and C, can both ...

Re: Database snapshot

How was the "winrate" for each position determined? I suspect it is logistic function based on score. The score is from "the scores been back-propagated using a weighted averaging function" see first post of this thread. In javascipt when winrate is missing (by design) for mate scores, I use // 201...

Re: Database snapshot

Thanks. Nice idea, to automate the creation of an opening book. Unfortunately, depth 22 is way too low to provide a reliable foundation, since most of the leaf positions are quiet and positional in nature. Unfortunately, such a data set which is better in both quality and quantity does not yet exis...
