cheng3 1.07 released

[Martin Sedlak]

Hi all,

the new version of cheng is available here as usual: http://www.vlasak.biz/cheng/
Thanks go to Jim Ablett who was kind enough to build the Windows PGO versions for me and of course Emil Vlasak for hosting.

Changes: some minor eval tweaking, futility pruning at higher depths, removed old ugly zobrist table. It's still ugly but 400kB worth of source code smaller. Estimated elo gain: +20 to +30 but I was wrong many times before anyway.

Note that this version supports personality files, see readme. There should be a plenty of parameters to play with.

There are also experimental Linux and OSX builds (both x64 only, no tablebases because I'm too lazy). Should work fine under XBoard + polyglot (tested in Ubuntu) and under SigmaChess (OSX).

have fun!

PS didn't know where to post it here on WB forum so I'm sorry if it doesn't belong here...

Thanks Martin!

I have moved the topic to the Winboard and related topics subforum. Normal people are certainly interested as well, not only programmers

A fixed version is available from now on http://www.vlasak.biz/cheng.
Fixed a really stupid bug where GTB configuration was hidden (thanks to Werner Schulle for finding it)
Agains thanks to Jim and Emil for swift responses.
I strongly recommend Windows users with GTBs to update.
My apologies

Martin
