El Ajedrecista
''El Ajedrecista'' ( en, The Chess Player) is an automaton built in 1912 by Leonardo Torres y Quevedo in Madrid, one of the first autonomous machines capable of playing chess. As opposed to the human-operated The Turk and Ajeeb, ''El Ajedrecista'' was a true automaton built to play chess without human guidance. It played an endgame with three chess pieces, automatically moving a white king and a rook to checkmate the black king moved by a human opponent. The device could be considered the first computer game in history. 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. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1912 In Chess
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 '' Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Chess Automatons
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, t ...

History Of Chess
The history of chess can be traced back nearly 1500 years to its earliest known predecessor, called chaturanga, in India; its prehistory is the subject of speculation. From India it spread to Persia. Following the Arab invasion and conquest of Persia, chess was taken up by the Muslim world and subsequently spread to Spain and the rest of Southern Europe. The game evolved roughly into its current form by about 1500 CE. "Romantic chess" was the predominant playing style from the late 18th century to the 1880s. Chess games of this period emphasized quick, tactical maneuvers rather than long-term strategic planning. The Romantic era of play was followed by the Scientific, Hypermodern, and New Dynamism eras. In the second half of the 19th century, modern chess tournament play began, and the first official World Chess Championship was held in 1886. The 20th century saw great leaps forward in chess theory and the establishment of the World Chess Federation. In 1997, an IBM super ...

IEEE Annals Of The History Of Computing
The ''IEEE Annals of the History of Computing'' is a quarterly peer-reviewed academic journal published by the IEEE Computer Society. It covers the history of computing, computer science, and computer hardware. It was founded in 1979 by the AFIPS, in particular by Saul Rosen, who was an editor until his death in 1991. The journal publishes scholarly articles, interviews, "think pieces," and memoirs by computer pioneers, and news and events in the field. It was established in July 1979 as ''Annals of the History of Computing'', with Bernard Galler as editor-in-chief. The journal became an IEEE publication in 1992, and was retitled to ''IEEE Annals of the History of Computing''. The 2020 impact factor was 0.741. The current editor in chief is Gerardo Con Diaz with the University of California, Davis.

Electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil. The magnetic field disappears when the current is turned off. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet. The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field. Electromagnets are widely used as components of other electrical devices, such as motors, generators, electromechanical solen ...

Portable Game Notation
Portable Game Notation (PGN) is a standard plain text format for recording chess games (both the moves and related data), which can be read by humans and is also supported by most chess software. History PGN was devised around 1993, by Steven J. Edwards, and was first popularized and specified via the Usenet newsgroup rec.games.chess. Usage PGN is structured "for easy reading and writing by human users and for easy parsing and generation by computer programs." The chess moves themselves are given in algebraic chess notation using English initials for the pieces. The filename extension is .pgn. There are two formats in the PGN specification, the "import" format and the "export" format. The import format describes data that may have been prepared by hand, and is intentionally lax; a program that can read PGN data should be able to handle the somewhat lax import format. The export format is rather strict and describes data prepared under program control, similar to a pretty printe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endgame Tablebase
An endgame tablebase is a computerized database that contains precalculated exhaustive analysis of chess endgame positions. It is typically used by a computer chess engine during play, or by a human or computer that is retrospectively analysing a game that has already been played. The tablebase contains the game-theoretical value (win, loss, or draw) in each possible position, and how many moves it would take to achieve that result with perfect play. Thus, the tablebase acts as an oracle, always providing the optimal moves. Typically the database records each possible position with certain pieces remaining on the board, and the best moves with White to move and with Black to move. Tablebases are generated by retrograde analysis, working backward from a checkmated position. By 2005, all chess positions with up to six pieces, including the two kings, had been solved. By August 2012, tablebases had solved chess for almost every position with up to seven pieces, but the positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
