Webpolymatrix game that is zero-sum the Nash equilibrium can be easily found by linear programming (and in fact by a quite direct generalization of the linear programming formulation of two-person zero-sum games). Informally, a polymatrix game (or separable network game) is defined by a graph. The nodes of the graph are WebThe prototypical family of large network games is that of polymatrix games. These games merge two classical concepts, two-player games and networks. In a polymatrix game, each player corresponds to a node in a network, and each edge encodes a two-player game between the two endpoints of the edge. A player’s payo is the sum of her payo s across
WebWe study the computational complexity of finding or approximating an optimistic or pessimistic leader-follower equilibrium in specific classes of succinct games—polymatrix … WebPolymatrix games can be seen as a generalization of games between two players in a sense that any interaction between two players can be represented as a classical bimatrix game and the outcome of this interaction can be interpreted independently of any other player. Researchers found some polymatrix games with interesting computational properties.
WebJan 27, 2016 · Abstract. We show that in zero-sum polymatrix games, a multiplayer generalization of two-person zero-sum games, Nash equilibria can be found efficiently with linear programming. We also show that the set of coarse correlated equilibria collapses to the set of Nash equilibria. In contrast, other important properties of two-person zero-sum … Webmultiplayer zero-sum 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 generaliza-
WebA constructive existence proof is given for equilibria of polymatrix games. The construction is based on a generalization of the almost-complementary paths used for the linear complementarity problem.
