decision variable


A decision variable represents a problem entity for which a choice must be made. For instance, a decision variable might represent the position of a queen on a chessboard, for which there are 100 different possibilities (choices) on a 10x10 chessboard or the start time of an activity in a scheduling problem. Each possible choice is represented by a [..]
