About pawn hash tables

I thought to find how much speed improvement I can get by pawn hash tables for part of the evaluation that depedenent only on pawn structure but I find that it is not so simple. The problem is that I have opening evaluation and endgame evaluation and I calculate average of them for every pawn based ...

Re: Movei403 progress 4 6 10 is stronger at slower time

your results are good. In 6 games everything can happen. In my opinion more amazing is the 9.5:0.5 that the default version got against fruit2.0 in the first 10 games only to lose 9.5:0.5 in the last 10 games of the match. Thanks for your testing I admit that I did not test 4 6 10 Here are some resu...

Re: 10th aniversery of deep blue win: interesting news artic

No, that is not what I'm saying at all. I'm saying given time the GM would adapt his or hers play accordingly, which would fit computer play at the expense of his/her human training. GM's are far too good to need to set traps, that's an insult to all GM's! This really shows the lack of understandin...

Re: Test position

I wish I could present a nice combination by Glaurung 2, but although my new engine wins more games than it loses against its older brother, it always wins in ugly and boring ways. The position given below, therefore, is from one of the games were Glaurung 1.2.1 won against the new Glaurung: [D]rq1...

detecting clones by comparing exe files

I wonder if there is a program that compare exe files and find the biggest common string that both exe files share and I wonder if this can be effective to help detecting clones. From the discussion about strelka: "...try to find the following sequence of bytes in Strelka: AD 8E 57 4E 87 11 E7 You c...

Re: An hard test position

I use to play OTB and finished with 1798 USCF. In looking at this hard position, I am extremely impressed with the play of white. I wonder that the expert (black) actually felt good about the position and was wondering if to accept a draw or press for the full point. Very nice position and move, es...

Re: Preliminary list of participants for ICT 7

Well, I explicitly inquired if the rules allowed it. It seems they do as long as it are totally unrelated programs, as uMax and Joker are. Unfortunately 2 times 0 is still 0. It seems all other contestants have at least 400 rating points more as the last measured rating of my engines. I think that ...

Re: Movei00_8_403 vs Petir439 ended 24.5 to 15.5

40 games Movei scored 24.5 simple math tells me that petir scored 15.5 and also if you count the points you can find that it scored 15.5 I think that the difference is small and the number of games that were played are not enough to get a conclusion about which version is best. I played more games ...
