from Pattern Recognition [4] :

A Professor Emeritus at Northwestern University, he served on the faculty for 30 years, teaching in the Computer Science department, the Psychology department, and the Kellogg Graduate School of Management. While at Northwestern, his research focused on machine learning and computer-based decision systems. He is the author of over fifty academic publications and several commercial software products. Peter graduated magna cum laude from Yale University and earned his Ph.D. in experimental psychology at the University of Wisconsin.

Brute-force and AI

During the 70s and 80s, Peter W. Frey researched and wrote on computer chess with further impact on the development. In disagreement with the AI-establishment and their decreasing interest in (brute force) computer chess as the former Drosophila of AI [5] , and unlike perhaps his colleagues De Groot and Gobet, he was an advocate of brute force Shannon Type-A programs. His suggestion to Slate and Atkin triggered some thoughts on the matter, and as a result they dumped selective searching in 1973 in favor of full-width searching in Chess 4.0 [6] .

Chess 0.5

In 1978, Peter W. Frey wrote a didactic program in Pascal along with Chess author Larry Atkin, which was published as Chess 0.5 in Byte Magazine [7] , and re-published on-line in 2005, available from Scott A. Moore's sites [8] [9].



Further working with Larry Atkin, Peter W. Frey is co-author of the strong commercial Othello program Odin [10] [11], which ran as module in the Chafitz Modular Game System and the Applied Concepts Great Game Machine [12].
Odin, Thor and Freyr [13]
