- a. If aij is a saddle point, then aij is the smallest entry in row i and the largest entry in column j.
- b. Each pure strategy is an optimal strategy.
- c. The value vR of the game to player R is the maximum of the values of the various possible strategies for R.
- d. The Fundamental Theorem for Matrix Games shows how to solve every matrix game.
- e. If column t dominates some other column in a payoff matrix A, then column t will not be used (that is, have probability zero) in an optimal strategy for (column) player C.
