Also, I don't know or have any responsibility towards any of the technical, marketing, or management people involved with Deep Blue. I wouldn't recognize Hsu if he walked up to me on the street and punched me in the nose. I'm not trying to stick up for IBM here -- that's not my job, and they certainly wouldn't pay me for it, anyway. Now that that's over.... The above statement can be found at http://www.research.ibm.com/deepblue/meet/html/d.3.3a.html#ai which is apparently a web page put together before the second Kasparov-Deep Blue match. Using the above statement to claim that Deep Blue had a simple evaluation function is a clear misunderstanding of the paragraph's internal and external context. From that statement, all that one can reasonably derive is that Deep Blue has a simpler eval function than the human brain, and that it does not try to emulate human thinking. One can't derive that Deep Blue has a simple eval function compared to other chess programs and systems -- nowhere in that statement is that implied.
