Research Type Theoretical In this paper, we provide the first Fully Polytnomial Time Approximation Scheme (FPTAS) for computing an MSNE in any symmetric multilinear RGG where its constraint moralized resource graph has bounded treewidth. Our FPTAS can be generalized to compute optimal MSNE, and to games with a constant number of player types. As a consequence, our FPTAS provides new approximation results for security games, network congestion games, and bilinear games. Our algorithm makes use of a compact, primal-dual formulation of the MSNE condition. We then use a treedecomposition based dynamic programming approach to solve the resulting feasibility problem, passing partial assignments of primal and dual variables and partial sums of constraints across subgraphs. We omit all proofs in this version. A longer version of the paper with proofs and more discussion is available on the authors websites.
