but you can not dispute that I and Robert Hyatt got the same result: that crafty 23.2 is better.

I got it after 10 games, he after 40 000 games.

fortuity? no no.

this compile of 23.2 32 bit is on my computer faster than JA 23.1 32 bit compile.

I see another new feature when running crafty in console mode.
typing hash 199M I get
Warning-- xboard 'memory' option disabled
and when running crafty with an input file I get that message several times. I don't use xboard.

Eigenmanns EET gives

Code: Select all

Crafty23.2   2_proc  64-bit egtb: not used      60 sec
number right......................     75
total nodes searched.............. 19469126621
average search depth............. 16.4
nodes per second..................  6958453
total time........................       46:37
solving 75 positions in a minute without egtbs. This looks pretty good. Kind regards

timecontrol 2min + 2 sec:

Crafty-23.2-win32 - Crafty_23.1_ja : 6,5/10 5-2-3 (=01==10111) 65% +108

bad: 2 games got lost:(

games soon:


question to:

Crafty-23.2 2661 3 3 40000 60% 2583 23%
Crafty-23.1 2638 3 3 40000 57% 2583 23%

what timecontrol was it?
10min + 2sec inc

I don't normally test that slowly, but we had changed the time usage/allocation code and I wanted to test at longer time controls in addition to our normal fast tests.

I have one question to Peter:
Your crafty.rc download looks like that:
mt=2
egtb
hash=384M
hashp=128M
cache=32M
ponder=off
smpnice=1
log=off
exit

Why do you use still smpnice=1? Is it still necessary?

best wishes
Werner
That is the default value, so it isn't needed, but doesn't hurt. I don't use that myself, but since real games are never ponder=off, smpnice is irrelevant anyway.
