Two Methods for Solving Constrained Bi-Matrix Games

In real life there are game problems in which players face with certain restrictions in the choice of strategy. These decision problems lead to constrained games. The quadratic programming problem equivalent to a constrained bi- matrix game is shown which provides a general method solving constrained bi-matrix games and shows a perfect corre- spondence between games and programming problems. Besides, a two-step method for constrained games is proposed whose theme is transforming the constrained game into an equivalent ordinary game. In the end, an example is shown to illustrate consistency of the two methods.
