Matriz de silla en juegos rectangulares

Summary

The saddle-matrix is defined as a generalization of the saddle-point for rectangular games. Let Γ₁ be the rectangular game whose matrix is the saddle-matrix and Γ the first considered rectangular game. Then one optimal strategy of the game Γ can be obtained from every optimal strategy of the game Γ in the following way: We write a zero for every row or column ommitted in writing the saddle-matrix. So the saddle-matrix appears as a generalization of the relations of dominance between rows or colums of the initial matrix. Some others properties of the optimal strategies of the saddle-point are considered.
