Game Description Language
Game Description Language, or GDL, is a logic programming language[1] designed by Michael Genesereth as part of the General Game Playing Project at Stanford University, California. GDL describes the state of a game as a series of facts, and the game mechanics as logical rules. GDL is hereby one of alternative representations for game theoretic problems.[2]
Quoted in an article in New Scientist, Genesereth pointed out that although Deep Blue is able to play chess at a grandmaster level, it is incapable of playing checkers at all because it is a specialized game player.[3] Both chess and checkers can be described in GDL. This enables general game players to be built that can play both of these games and any other game that can be described using GDL.
GDL is a variant of Datalog, and the syntax is largely the same. It is usually given in prefix notation. Variables begin with "?".[4]
