pay-off matrix

pay-off matrix
A matrix showing the pay-offs to each player in a two-sided game. The rows show the results of each choice of strategy by one player, and the columns the results of each strategy choice by the other. There may be one matrix for the pay-offs to each player; alternatively, each box in a pay-off matrix may contain two figures, for the pay-offs to the two players. In a zero-sum game the pay-offs to the second player are equal and opposite to those for the first, so only one set needs to be shown explicitly.
