Where is Computer Chess Going?

A technical session titled Where is Computer Chess Going was moderated by Tony Marsland, with Hans Berliner, Monroe Newborn, Murray Campbell, Robert Levinson and Jaap van den Herik attending as panelist [7] . At one point the discussion went on brute strength versus trimming techniques - Campbell replied that both approaches will eventually succeed. Larry Kaufman commented from the audience that selective searches outperform full width on comparable hardware. Don Dailey mentioned that one main goal is to beat the World Champion. He asked "How long will it take to cross the extra distance and play a perfect game?". Berliner replied, "Centuries! A perfect game is a science-fiction dream". Further, Robert Levinson gave a presentation of his Morph project.
