-Two years after 5.3.0 there is a new version of OliThink. A little bug was removed. This seems to improve about 35 ELO. -Furthermore the Java Version, which seems to be the best Java Engine available, has been revised. -Note, that the Java Version on a 64bit Java Runtime Environment is as strong as the native one on a 32bit System. -MacOSX binaries added. Download here as usual: http://home.arcor.de/dreamlike/chess/index.html The x64 Windows binary hasn't been tested yet. Please check it out and tell me, if it doesn't work.

Hello !

Thank you Mr. Olivier for the long avaited OliThink 5.3.1 J !
This your engine is for sure the best Java WB chess engine but only the place 3/4 - th ( together with Magnum 3.00 r20 JA) in the Java world. My very long SUPREME JAVA TOURNAMENT shows me CuckooCkess 1.12 ( by far) and Flux 2.2 like the best Java chess engines !

Thank you again !

It would be a fine thing to add analyse mode to the Linux compile. _________________ Marek Soszynski

I don't know if you saw my email, but there is a bug about the move format. Really a trivial fix

=> replace

Code:

printf("%d. ... ", COUNT/2 + 1);

Code:

printf("move ");

the "%d. ... %s" format is antiquated xboard stuff that doesn't work with some modern interfaces. better to use "move %s", simply.

I'm currently running Olithink 5.3.1 in my Open Source Bullet rating list (1'+1"). Results available tomorrow in the tournament forum.

Hi Lucas, I got your email, but forget to change this. I did it now and re-uploaded the files with this change.

Of course, I could transfer Stockfish into Java as I did with OliThink. Only problem is, that I will need at least one week full work, because of the excessive use of pointers and c++ specific stuff.

Hi Maestro Oliver !

That's ( but not only) an explanation why I love Java : all 30 chess engines I have are original works . The strenght isn't so important for me. I like a lot - for example Animats Chess rev23-a nice Australian Chess engine (Mr.Stuart Allen). Also I like to play myself with BremboCE , Carballo...................
Well , I know that CuckooChess has some nice features: a strong (and small) engine book- inntegrated in the .exe , endgame bitbases (also integrated). Flux is also a true phenomenon: a low speed and depth but a superb evaluation function ( made by Mr. Nanova).
It's a true passion for me to study every new Java chess engine. Even the unfinished ones ( like the Romanian Black&Right-very buggy , the unfinished Norvegian Mentally Challenged rev.1 , the impossible Italian PsychoChess 0.1 or the Duch move generator POS-1.2 (DeepBrutePOS)..........).

So , THANK YOU again for the new OliThink 5.3.1 J.

Have a nice day !
SilvianR
