IE I couldn't begin to tell you how many "GP instructions" it would take to do my eval in Cray Blitz. Without a _lot_ of work. He said it had about 8K weights. Maybe he simply said "OK, 8K weights = 8K patterns to match = 8K comparisons, 8K branches, 8K instructions, 8K branches around the else, and 8K instructions for the else: If (P) s1 else s2; that would be a _wild_ guess. And might be within a factor of 10 or so of reality. who knows? As far as "95% right about the eval" how do you assess that? Knowing _nothing_ about deep blue II...
