5.17 We have assumed that the rules of each game define a utility function that is used by both players, and that a utility of x for MAX means a utility of — x for MIN. Games with this property are called zero-sum games. Describe how the minimax and alpha-beta algorithms change when we have nonzero-sum games—that is, when each player has his or her own utility function. You may assume that each player knows the other's utility function.
