Board representation in computer chess is a data structure in a chess program representing the position on the chessboard and associated game state. [1] Board representation is fundamental to all aspects of a chess program including move generation, the evaluation function, and making and unmaking moves (i.e. search) as well as maintaining the state of the game during play.
A chessboard contains natural corners at the boundaries between board squares, so one would expect corner detection algorithms to successfully detect them in practice. Indeed, the following figure demonstrates Harris corner detection applied to a perspective-transformed chessboard image. Clearly, the Harris detector is able to accurately detect ...
In 1965, Richard Bellman proposed the creation of a database to solve chess and checkers endgames using retrograde analysis. [11] [12] Instead of analyzing forward from the position currently on the board, the database would analyze backward from positions where one player was checkmated or stalemated. Thus, a chess computer would no longer ...
There are other symbols used by various chess engines and publications, such as Chess Informant and Encyclopaedia of Chess Openings, when annotating moves or describing positions. [8] Many of the symbols now have Unicode encodings, but quite a few still require a special chess font with appropriated characters.
Algebraic notation. Algebraic notation is the standard method for recording and describing the moves in a game of chess.It is based on a system of coordinates to uniquely identify each square on the board. [1]
A chess engine generates moves, but is accessed via a command-line interface with no graphics. A dedicated chess computer has been purpose built solely to play chess. A graphical user interface (GUI) allows one to import and load an engine, and play against it. A chess database allows one to import, edit, and analyze a large archive of past games.
Forsyth–Edwards Notation (FEN) is a standard notation for describing a particular board position of a chess game. The purpose of FEN is to provide all the necessary information to restart a game from a particular position. FEN is based on a system developed by Scottish newspaper journalist David Forsyth.
Computer chess IC bearing the name of developer Frans Morsch (see Mephisto). Chess machines/programs are available in several different forms: stand-alone chess machines (usually a microprocessor running a software chess program, but sometimes as a specialized hardware machine), software programs running on standard PCs, web sites, and apps for mobile devices.
