Donald Michie

Donald Michie (; 11 November 1923 – 7 July 2007) was a British researcher in artificial intelligence. During World War II, Michie worked for the Government Code and Cypher School at Bletchley Park, contributing to the effort to solve "Tunny", a German teleprinter cipher. Early life and education Michie was born in Rangoon, Burma. He attended Rugby School and won a scholarship to study classics at Balliol College, Oxford. In early 1943, however, looking for some way to contribute to the war effort, Michie instead attempted to enrol on a Japanese language course in Bedford for intelligence officers. On arrival, it transpired that he had been misinformed, and instead he trained in cryptography, displaying a natural aptitude for the subject. Six weeks later, he was recruited to Bletchley Park and was assigned to the "Testery", a section which tackled a German teleprinter cipher. During his time at Bletchley Park he worked with Alan Turing, Max Newman and Jack Good. Michie and Good were on the initial staff of the Newmanry. Fom 1945 to 1952 he studied at Balliol College, Oxford. He received his Doctor of Philosophy (D Phil) degree for research in mammalian genetics, in 1953. Career and research In 1960, he developed the Matchbox Educable Noughts And Crosses Engine (MENACE), one of the first programs capable of learning to play a perfect game of noughts and crosses. Since computers were not readily available at this time, Michie implemented his program with about 304 matchboxes, each representing a unique board state. Each matchbox was filled with coloured beads, each representing a different move in that board state. The quantity of a colour indicated the "certainty" that playing the corresponding move would lead to a win. The program was trained by playing hundreds of games and updating the quantities of beads in each matchbox depending on the outcome of each game.
