Octochess r4984 released

[Codesquid]

A new version of Octochess has been released, you can download it from http://octochess.org/

This version introduces a new threading implementation to better utilize multiple CPU cores. In previous versions, using multiple cores resulted in little to no gain in strength. In this new version, there's now a measurable gain.

Various improvements have been made to the evaluation and the search code, this should further increase strength.

Last but not least, you can now run Octochess on a jailbroken Kindle Touch.

The changes in all their (in)comprehensible glory:

• Add support for ARM architecture to run Octochess on Kindle Touch
• New threading implementation
• Implement 50-move rule
• Evaluation improvements
• Implement pondering in UCI mode
• Add support for commands to limit search depth
• Fix rare bug in move generator
• Implement mate-distance-pruning
• Fixes to futility pruning
• Fixes to LMR depth reduction
• Handle KBPvKP endgame, improve KPvK
• Various cleanup

Looking forward to trying it out.

Thank you Tim. Sounds great. I will use it as a sparring partner for DiscoCheck, along with Gaviota 0.86 and Fruit 05/11/03.

PS: Is it possible to put the opening book in a separate file, so as to make the download package smaller (source code and engine only) ?

Congrats Tim!

So it does nor run in 32 bits windows?

I'll consider this for the next version.

While I don't provide any binaries for legacy 32bit Windows, you can still compile it yourself for 32bit Windows.

Tim, I do not know even what "compile" means. I am a writer, not a computer geek.

Thanks. I will test it. I like your engine and FileZilla.

A compiler is a program that takes a source written into one language and translates it into another language, usually machine language (the only language your computer really understand).

So, now you know: a compiler is a translator. Something that, as a writer, you certainly understand.
