报告题目：An Operator Splitting Approach for Solving Multi-Stage Stochastic Generalized Nash Equilibrium Problem

报告摘要：In this talk, we consider a class of multi-stage stochastic generalized Nash equilibrium (SGNE) problem with expected-value cost functions, where the feasible decision sets of all players are coupled together by a globally shared affine constraint. Upon utilizing the variational SGNE (v-SGNE) as a refined solution, the problem is reformulated as that of identifying the zeros of a sum of monotone operators through the integration of nonanticipativity constraints, primal-dual analysis and an augmentation of variables. We first propose a v-SGNE searching algorithm based on forward-backward operator splitting methods for solving the two-stage SGNE. Then we demonstrate the convergence of the proposed algorithm for fixed step-sizes under some mild assumptions. Subsequently, we extend the proposed method and its convergence result to the multistage case. This is a joint work with Hailin Sun.
