Re: Rybka 4.1
Showing 9 elo right now. Is that a ~ 1 elo per month improvement rate or do I have the wrong release dates?

Re: Rybka 4.1
I think the elo gain is statistical randomness, as Vas stated that he did not change anything related to eval or search. This was a bug fix release, mostly related to stall bugs.

Re: Rybka 4.1
There 9 ELO improvement you are referring to is from the 6CPU version of Rybka 4 and the 4 CPU version of Rybka 4.1

Re: Rybka 4.1
Why doesn't CCRL test Houdini with 4 cores? Why just test it with 1 core?

Re: Rybka 4.1
Rybka 4.1 is only a bug fix with no ELO strength increase by way of evaluation improvement. Of course the stall bug was very serious and should improve ELO strength, especially in games where depth 13 or more are reached frequently.

Let's see what happens in TCEC Elite match: Rybka 4 scored 16,5-23,6 = -60 ELO. Interesting match coming with super hardware!

Re: Rybka 4.1
Can someone clear the confusion for me about "Rybka" and "Deep Rybka"? How are they the same or different?
Is "Deep Rybka 1CPU" the same as "Rybka"?
