Crafty 23.4

[bob]

I just released the source for 23.4 on my ftp box (ftp.cis.uab.edu/pub/hyatt). It has some cleanup, duplicated search/quiesce functions are gone, plus a few qualitative changes that provide +12 Elo or so on our testing.

Has one timing fix for Frank Q's testing that should prevent time losses right at the time control...

Hi Bob,

thats great!

So I wait of the JA version by Jim Ablett and will add the new version in the yesterday started SWCR-64 tourney.

Have a look here (live table)
http://www.amateurschach.de/ftptrigger/64-bit.html

No problem to add Crafty 23.4 JA x64 a little bit later in the still running tourney.

Thanks for your service!

Best
Frank

Ditto. great news.

Hope that chessbase makes a cb native engine, crafty 23.04.eng or .engine
to work with new chessbase products such as CB11, DF12, DR4 etc.
Latest one was 23.01 if I remember correctly.

Does this version have a fix for the unusually strong play seen when SKILL=1 is set?

Thanks for the new Crafty.

Before I try this, has the problem with gcc been identified and fixed. I'm referring to http://talkchess.com/forum/viewtopic.ph ... 60&t=35609

Yes, as did the last version, so far as I know...

I actually do not know. Our cluster compilers do not get upgraded often, since what works is "good enough" and avoids introducing errors that could take weeks to recover from if invalid data is produced by a compiler glitch...

I have compiled versions for those who can't compile themselves at:

Crafty Win32/64 Builds

Enjoy,

I'm having a lot of trouble running my Linux compiles with the new src. (my Linux system is Mint (debian based). This is 32 bit. I haven't tested
64 bit yet.
I get same error with both GCC & Intel.
