It created great excitement when it made its debut, at the University of Paris in 1914. It was first widely mentioned in ''Scientific American'' as "Torres and His Remarkable Automatic Devices" on November 6, 1915.〔''Torres and his remarkable automatic devices''. Issue 2079 of Scientific American, 1915〕 Using electromagnets under the board, it automatically played an endgame with three chess pieces, moving a king and a rook to checkmate a king moved by a human opponent. The device is considered the first computer game in history. The automaton does not deliver checkmate in the minimum number of moves, nor always within the 50 moves allotted by the fifty-move rule, because of the simple algorithm that calculates the moves. It did, however, checkmate the opponent every time. If an illegal move was made by the opposite player, the automaton would signal it.〔Atkinson, George W. (1998). ''Chess and machine intuition''. Intellect Books, pp. 21-22. ISBN 1-871516-44-7〕 Its internal construction was published by H. Vigneron.〔H. Vigneron: Robots. English Translation in: David Levy, Monty Newborn: ''Chess and Computers'', pp. 13-23. Computer Science Press, 1982.〕 Leonardo's son Gonzalo made an improved chess automaton based on El Ajedrecista in 1920, which made its moves via magnets located under the board.〔Brian Randell, From Analytical Engine to Electronic Digital Computer: The Contributions of Ludgate, Torres and Bush. ''Annals of the History of Computing'', Vol. 4, No. 4, Oct. 1982〕 Both are still working and are on display at the ''Colegio de Ingenieros de Caminos, Canales y Puertos'' in Madrid. As opposed to the human-operated The Turk and Ajeeb, ''El Ajedrecista'' was a true automaton built to play chess without human guidance. ==Notes== 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「El Ajedrecista」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
