Mac Hack is a computer chess program written by Richard D. Greenblatt. Also known as Mac Hac and (The Greenblatt Chess Program ), it was developed at the Massachusetts Institute of Technology. Mac Hack VI was the first chess program to play in human tournament conditions, the first to be granted a chess rating, and the first to win against a person in tournament play. Its name comes from Project MAC ("Multi-Level Access Computer" or "Machine-Aided Cognition") a large sponsored research program located at MIT. Over time, it became a hack in the sense of ''Hackers: Heroes of the Computer Revolution'',〔: *〕 a book by Steven Levy in which Greenblatt appears. The number VI refers to the PDP-6 machine for which it was written. ==Development== Greenblatt was inspired to write Mac Hack upon reading MIT Artificial Intelligence Memo 41,〔 *〕 or a similar document describing Kotok-McCarthy, which he saw while visiting Stanford University in 1965. A good chess player, he was inspired to make improvements at MIT in 1965 and 1966. In about 2004, he had an opportunity to tell Alan Kotok that "7 7" would have done better than "4 3 2 2 1 1 1 1 0 0" in Kotok-McCarthy's REPLYS subroutine which generated each player's next plausible moves.Greenblatt added fifty heuristics that reflected his knowledge of chess. Mac Hack was written in MIDAS macro assembly language on the PDP-6 computer DEC donated to MIT (the first working PDP-6, serial number 2). Many versions may exist. During this period the program was compiled about two hundred times. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mac Hack」の詳細全文を読む スポンサード リンク
