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!
Martin

Re: cheng3 1.07 released
Well it should be there... I added a test for not reporting gtb-related parameters when no gtb is found (needed that for Linux and OSX builds as I have no gtb support there)Werner wrote:Thanks Martin,

It's safe because it doesn't report gtb parameter only if gtb wouldn't be used anyway. Have you had any tbhits in the previous version?

Re: cheng3 1.07 released
Hi,
I miss the uci parameters for gtb:
opening book not found
uci
id name cheng3 1.07 JA
id author Martin Sedlak
option name Hash type spin min 1 max 1024 default 4
option name Clear Hash type button
option name Ponder type check default true
option name Skill type spin min 0 max 100 default 100
option name MultiPV type spin min 1 max 256 default 1
option name OwnBook type check default true
option name PersonalityFile type string default
uciok
yes- I have had tbhits with 1.06 - but no with new version?
The engine should know where the gtbs are stored.

Re: cheng3 1.07 released

Thanks also from me. Would it be possible for you to get me the address of the girl/woman/lady, whatever, in the picture on your site where she is removing something from her purse?

create gtb directory in the root (on the disk from which you run the engine) and copy in the 3-man files only. It should enable you to change the path.
