People have before played against other programms, but this was cumbersome. Since then the development is a (co-)evolution. The programmers react on the ideas of others. It is some sort of silent conversation. E.g. when Shredder came with his impressive search depths, the other programmers had to react too. One can not sit there and watch how Shreddere outsearches one ones creation. One also knows: There is stil a lot of potential in pruing. After all it works in Shredder. The same will happen with Rybka. It has the advantage of being a new species which is somewhat different to the current population. But the ecosystem will react on Rybka. Thats the way evolution works. A concrete Hydra-example: In the Match Topalov-Hydra, Bilbao 2004, Hydra got a passed pawn on d3 and was very happy about the position. Actually the idea was quite bad and we almost lost the game. So we reduced the value of central-passed pawns in the Middlegame. Rybka does not know about this and likes to push his d/e pawn. Hydra does not care, because it was told to avoid the "Topalovmatch-pawn-push" (it works always in both directions). I have increased the bonus now again slightly to avoid this problem against Rybka. And I will probably kick myself in the ass, if Hydra makes against a top GM the next time the same stupid move like in Bilbao. Chrilly
