چکیده

Strictly competitive games are a class of 2-player games often quoted in the literature to be a proper generalization of zero-sum games. Other times it is claimed, e.g. by Aumann, that strictly competitive games are only payoff transformations of zero-sum games. But to the best of our knowledge there is no proof of such claim. We shed light to this point of confusion in the literature, showing that any strictly competitive game is indeed a payoff transformation of a zero sum-game; in fact, an affine transformation. We offer two proofs of this fact, one combinatorial and one algebraic.

On minmax theorems for multiplayer games Citation

We prove a generalization of von Neumann’s minmax theorem to the class of separable multiplayer zerosum games, introduced in [Bregman and Fokin 1998]. These games are polymatrix—that is, graphical games in which every edge is a two-player game between its endpoints—in which every outcome has zero total sum of players’ payoffs. Our generalization of the minmax theorem implies convexity of equili...

Iterated Weak Dominance in Strictly Competitive Games of Perfect Information

We prove that any strictly competitive perfect-information two-person game with n outcomes is solvable in n−1 steps of elimination of weakly dominated strategies— regardless of the length of the game tree. The given bound is shown to be tight using a variant of Rosenthal's centipede game.

Game Theory Lecture

A two person zerosum game is of the form 〈{1, 2}, S1, S2, u1,−u1〉. Note that when a player tries to maximize her payoff, she is also simultaneously minimizing payoff of the other player. For this reason, these games are also called strictly competitive games. Player 1 is usually called the row player and player 2 is called the column player . Let S1 = {s11, s12, . . . , s1m} and S2 = {s21, s22,...

A Game-Theoretic Analysis of Strictly Competitive Multiagent Scenarios

This paper is a comparative study of game-theoretic solution concepts in strictly competitive multiagent scenarios, as commonly encountered in the context of parlor games, competitive economic situations, and some social choice settings. We model these scenarios as ranking games in which every outcome is a ranking of the players, with higher ranks being preferred over lower ones. Rather than co...

Dynamic Competitive Supply Chain Network Design with Price Dependent Demand and Huff Utility Function

This paper develops a two-stage model to consider a franchise/franchisee environment in which supply chains are simultaneously entering the untapped market to produce either identical or highly substitutable products and give franchise to franchisees. Customer demand is elastic, price dependent and customer utility function is based on Huff gravity rule model. The supply chains, in the first st...
