We know 126M nodes directly from Hsu. see page 4 of the paper. We also know that the estimate for the efficiency of deeper blue was also 8-12% see page 18 I do not know if they mean 8-12% of 126M nodes or 8-12% of a different number. > >>2)They used more extensions. > >that could certainly possible... > >> >>I remember that you claimed that 2 is not correct but >>I did not see it in the paper. > > >I didn't say it wasn't correct. I said that deep blue's search was definitely >derived from deep thought's search. You said that the paper say exactly the opposite to the claim that they did more extensions and the paper does not say it see http://www.talkchess.com/forums/1/message.html?246929 Uri
