i have read the interview with GM E. Sveshnikov.
he expressed the opinion that Rybka is using his moves in sicilian,
he pointed that he was interested in the others engines and has told that analysing some engines he discovered that some of them Fritz, Hiarcs have the algorithms of searching move similar to the selected WCC but unfortunately he did not mentioned them.
is it able to use correlation to discover that,
i suppose that it needs to prepare test position on the base of the games of WCC.
Has someone done such an experiment and can share the results ?
