Murray Campbell [1]

Murray S. Campbell,
a Canadian computer scientist and chess player [2], most famous for being member of the Deep Blue team and beating Gary Kasparov in 1997. Campbell is actually a research scientist at the IBM T. J. Watson Research Center in Yorktown Heights, New York.


Computer Chess

Murray Campbell got hooked in computer chess at the University of Alberta in Edmonton, Canada, where he worked with Tony Marsland on parallel search and principal variation search [3] [4]. He left Canada to enroll at Carnegie Mellon University (CMU) as a doctoral candidate in computer science. Supported by his advisor Hans Berliner, he developed the chunking pawn endgame program Chunker, and received his Ph.D. in 1987 for his work on chunking as an abstraction mechanism in solving complex problems [5]. Along with Gordon Goetsch, he researched on the null move heuristic - none recursively with a modest depth reduction [6].

Campbell was member of the HiTech team around Berliner, while Feng-hsiung Hsu and Thomas Anantharaman were already developing ChipTest, the predecessor of Deep Thought. In 1986, Murray Campbell joined the ChipTest team and in 1989, Campbell and Hsu joined IBM to develop Deep Blue. Murray Campbell's main function in the Deep Blue team was the development of the evaluation function. He worked closely with the team's chess consultant, Joel Benjamin, in preparing the opening book [7].

Quotes

by Hans Berliner on Campbell's role in HiTech team [9]:

Murray Campbell has helped with the opening book, and has now implemented the Singular Search (Anantharaman 1988 [10]) algorithm on HiTech. He has been my alter-ego when it comes to discussion of chess ideas, and what can be done to allow HiTech to understand this or that.
