Decomposable Penalty Method for Generalized Game Problems with Joint Constraints

Abstract

We consider an extension of a noncooperative game problem where players have joint binding constraints. In this case, justification of a generalized equilibrium point needs a reasonable mechanism for attaining this state. We suggest to combine a penalty method together with shares allocation of right-hand sides, which replaces the initial problem with a sequence of the usual Nash equilibrium problems together with an upper level variational inequality as a master problem. We show convergence of solutions of these auxiliary penalized problems to a solution of the initial game problem under weak coercivity conditions.
