Hi John
I agree with you that the Edisonian approach is the best way to determine what
makes the improvement (if any)
My own experience ( as discussed with you earlier ) is that CM8K against CM8K
Utzinger settings is much of a muchness.
Now is this down to 1 or more factors like...
1/ How the engine works...after all they are both using the same engine.
so the "thinking methodology is similar/identical"
2/ Something else, that far more technically minded people than my good self
can make sense of.. ( more than likely )
I still believe;however my sample size is way too small to be conclusive [ JM
posted that he would want at least 1000 games to get a reasonable sample - I
agree that that should be a minimum]; is that against ANOTHER chess programs (in
this case - Fritz 6e) the Utzinger settings tend to come out of the opening book
in a better position.
In respect to matches against other computers:--
I have experiences of that for long periods of uptime CM8K can occupy 100% of
the CPU without doing a hell of a lot. ( Possible reason for SSDF scores? -
Thrashing??)
John - Have you any support calls into the CPU utilisation ( or give guidance
foe me on how to identify what is causing the problem - may be of use to you)
Cheers
Scott
