"WebAbstract. We introduce a new technique for proving membership of problems in FIXP: the class capturing the complexity of computing a fixed point of an algebraic circuit. Our technique constructs a “pseudogate,” which can be used as a black box when building FIXP circuits. This pseudogate, which we term the “OPT-gate,” can solve most convex … " - Polymatrix games

Polymatrix games

WebIn polymatrix coordination games, each player x is a node of a graph and must select an action in her strategy set. Nodes are playing separate bimatrix games with their neighbors in the graph. Namely, the utility of x is given by the preference she has for her action plus, for each neighbor y, a payoff which strictly depends on the mutual ... Webmultiplayer zero-sum games, introduced in [Bregman and Fokin 1998].
