Payoff Matrix
An 
Matrix which gives the possible outcome of a two-person Zero-Sum Game when player A has 
possible moves and player B 
moves. The analysis of the Matrix in order to determine optimalstrategies is the aim of Game Theory. The so-called ``augmented'' payoff matrix is defined as follows:
