That seems to be the main thrust of the "tricks," like alpha/beta. But these sorts of tricks have been around quite awhile now. They are almost becoming "Ho Hum." Wouldn't it seem unlikely that anybody will discover any surprising new trick for making the trees smaller? [Small evolutionary improvements but no big revolutionary one.] Bob Hyatt, for example, seems to be saying that alpha/beta cannot be generalized. It's a dead end. "No room for revolutionary improvements there," according to Bob H. : ) > >I believe that the evaluation also can be improved significantly. >Programs do not know about theoretical draws of KRPP vs. KR and it is only one >example. There is still a lot of discussion here about "knowledge," whatever that is. [I know the definition of "knowledge" in human terms, but not sure of the definition in the language of chess software.] Maybe that's where the advances will come from in the evaluation?
