UEC Cup 2019 (mini-Shogi)

Yesterday I received an e-mail from Takeshi Ito that there will be another UEC-Cup tournament for mini-Shogi at the upgoming GAT meeting, March 9-10. See here . As far as I understand from there it is an invitation-only tournament, unless you are a participant of the GAT meeting. So far it seems onl...

Re: Fairymax is using 25% of cpu

Now is your complaint that 25% is too high or too low?

25% seems normal usage, for a single-threaded engine running on a two-core (= 4 hyperthreads) system. Fairy-Max shouldn't use any CPU when not on move; it would just be waiting for input.

Re: Generate EGTB with graphics cards?

Perhaps KHEK is too small to be representative: with 25KB the entire EGT would easily fit in the level-2 cache, which is very fast. Could you also give me the building times for KRCKR? This has 59M positions. (Half of that when using symmetry. Does your generator make use of this symmetry?) This is ...

Re: Polyglot extension tool

There is a tool that can convert bin books to pgn called Cerebellum book CONVERTOR You would have to be careful with that, as converting Polyglot books to PGN is not generally possible. There is no way to convert the position keys in the book back to positions. So you would be dependent on followin...

Re: Generate EGTB with graphics cards?

Ah, you nearly fooled me! :wink: But KHEK only has 25K positions, with 2-fold symmetry (9*9*7*90/2), instead of 2M for KBNK with 8-fold symmetry (64*64*64*64/8). That is 80 times smaller. So it is not so fast at all: in stead of 2x faster than Marcel's "PrettyFast" generator it is 40 times slower. A...

Re: Generate EGTB with graphics cards?

Just to make absolutely sure there is no miscommunication: with KBNK you mean the Chess end-game. Not Xiangqi KHEK, right?

Re: Can somebody explain what makes Leela as strong as Komodo?

I did that for pawn structure patterns in earlier versions of Schooner. However, lack of sufficient training data gave unreliable results. It seemed to help a bit - but not enough to make a 100 elo of difference. Mostly I set intuitive values for "patterns" from experience. Are not stored position ...

Re: Analyze game for dummies

It is a de-facto standard to report scores in this format from the mover's point of view. It seems easy enough to spot blunders by ignoring the sign altogether. E.g. where the absolute value jumps from 1.75 to 4.44 there was probably a blunder.. Of course the recommended way is not by staring at the...
