chess4j 5.1 released

Post by jswaff »

Hi all,

I'm releasing v5.1 of my Java based engine, chess4j. Incidentally the change log is the exact same as Prophet 4.3. :)

They are. They didn't start out that way, but now they are exactly the same in terms of the search tree and end point evaluation. chess4j has an opening book, pondering, and an auto-tuner though, Prophet does not.

The Linux build of chess4j contains Prophet as a static library. It's enabled using the '-native' command line switch. It'll search 2-3x faster by dropping down into native code.

Thanks for the reply, now it's clear.
