Re: Opening book database?

IIRC, the Crafty approach is to break the book into many segments (I think 2^16 segments), and it would sequentially loop through just one of those segments, which is manageable. In a polyglot book the positions are ordered according to their (Zobrist) hash key. To find a particular key you can do ...

Re: Opening book database?

polyglot book format. I would strongly recommend the polyglot book format. I think it is important that GUI's, adapters and chess engines agree on a common open opening book format (rather than proprietary stuff like ctg or abk). The polyglot format has the advantage that it is easy to parse (see t...

Re: Arena or similar testing program for Linux - Own proggie

OpenSource, to use for everyone. if this is what you can call a "licence" Wink
I hope you didn't inteprete my question in a negative way. But an explicit license is necessary to be included in a Linux distribution for example.

Re: Arena or similar testing program for Linux - Own proggie

If anyone is interested in having a Testing Suite that runs platform independent without any GUI and without any CPU usage, please write here.
What is the license?

Best regards,

Re: Arena or similar testing program for Linux

If I want WinBoard engines to run with an external book, I run them through WB2UCI and Polyglot
.

Well that's a bit of a hack isn't it, using two(!) adapters to do what the GUI could be doing?
Not to mention that WB2UCI only runs on windows and is closed source AFAICS.

Re: Arena or similar testing program for Linux

Likewise, if a Human plays an engine, you would want the engine to use a book, not the Human. So what is against having the engine hande the book? Nothing. But I prefer the GUI handling the book. I have the impression that this is what most people prefer but I maybe wrong. Often you don't like the ...

Re: Arena or similar testing program for Linux

Well, that is exactly how it uses the loadGameFile. It forces the moves until they run out, and then the engines take over Hmm that seems to be quite different from an opening book. In xboard 4.2.7 (4.3 has not been packaged for Ubuntu) it seems that one of the games from the gamefile is selected, ...

Re: Arena or similar testing program for Linux

If you go back far enough, no option will be supported. That is what I meant by 'stone age'. Sorry, I don't see the need for sarcasm when people are posing honest questions. How would you want it to use a book? Like any GUI uses a book. The GUI uses the book until it runs out and then gives control...

Maybe this option is present in 4.3? It is not present in 4.2.7 which comes with Ubuntu 8.04.

Can xboard 4.3 now use its own book? If so in what format? I would assume polyglot since that is easy to parse and well understood.

Re: Arena or similar testing program for Linux

You may call xboard from a script. See e.g.

I would use python however, for more flexibility.
