In artificial intelligence and operations research, constraint satisfaction is the process of finding a solution to a set of constraints that impose conditions that the variables must satisfy. A solution is therefore a set of values for the variables that satisfies all constraintsвЂ”that is, a point in the feasible region.. The techniques used in constraint satisfaction depend on the kind of Constraint satisfaction is the group of problems in which finding the solution involves discovering a suitable group of parameters such that the that result falls with some pre-defined boundaries.

constraint satisfaction problem. вЂў A Constraint Satisfaction Problem consists of 3 components 1. A set of variables. 2. A set of values for each of the variables. 3. A set of constraints between various collections of variables. We must find a value for each of the variables that satisfies all of the constraints. Researchers in artificial intelligence (AI) usually adopt a constraint satisfaction approach as their preferred method when tackling such problems. However, constraint satisfaction approaches are not widely known amongst operational researchers. The aim of this paper is to introduce constraint satisfaction to the operational researcher.
