Rybka is without doubt stronger engine.Mike S. wrote:Although it's supported by FIDE, ICGA, Levy and ChessBase: It's just an exhibition match of two engines, which aren't Top-5 anymore. I think we should not pay too much attention. The various rating lists can provide comparisons for much more than just six games.
It is a shame that the loser wil receive 40,000 $ while stronger engines like Rybka, Hiarcs, Loop, Shredder etc. cannot participate.
There are ICGA members on this message board. What do YOU think? If it's not ok, what are you going to do?
Nothing...

Junior is a good, interesting and respectable engine! - But it has always been overestimated because of misleading ICGA tournament results.

I would like to see a match Rybka-Hydra. It doesn't have to be organized by FIDE, although it might be considered the absolute world championship of chess.Uri Blass wrote:Rybka is without doubt stronger engine.

Since when Deep Fritz 10 isn't in Top 5 anymore???Mike S. wrote:Although it's supported by FIDE, ICGA, Levy and ChessBase: It's just an exhibition match of two engines, which aren't Top-5 anymore.
Since it was surpassed by Rybka, Zap!Chess, Hiarcs, Naum, Deep Shredder and LoopMP. At least in our study: CCRL 40/40. (Not to mention Deep Junior which is 1 point ahead of Deep Fritz right now in our 40/40 list).rdan1987 wrote:Since when Deep Fritz 10 isn't in Top 5 anymore???
Uri, please note that the question "which engine is best" is of a metaphysical nature, and thus it is nonsensical to try and answer it in an absolute sense. All you can really do is making various tests and making various predictions (=creating an Elo list).Uri Blass wrote:I think that the difference is too small to claim which engine is betterMike S. wrote:Uri, please be serious.

when you consider that the better engine is dependent on the opening line
From CEGT 40/120
6 Deep Shredder 10 x64 2CPU 2858 17 17 925 51.5 % 2847 40.5 %
8 List 11.64 2CPU 2849 20 20 700 47.6 % 2866 40.0 %
12 Deep Junior 10 2CPU 2833 19 19 844 49.0 % 2840 33.8 %
I think that difference of less than 30 elo can be dependent on the opening book that is used and the question if ponder on or ponder off is used.
It is not the fault of CEGT and CCRL but it is impossible to claim without doubt which engine is better when the difference is small regardless of the number of games because engine X can be better in one opening when engine Y can be better in another opening and I see no objective way to decide how many games to play with every opening.
