| Research Type | Theoretical | In this work, we study congestion games in which each player s strategy space can be described compactly using a set of linear constraints. For instance, network congestion games naturally fall into this subclass as each player s strategy can be described by a set of flow constraints. We show that we can represent any mixed strategy compactly using marginals which specify the probability of using each resource. As a consequence, the expected utilities and the best responses can be computed in polynomial time. We reduce the problem of computing a best/worst symmetric approximate mixedstrategy Nash equilibrium in symmetric congestion games to a constraint optimization problem on a graph formed by the resources and the strategy constraints. As a result, we present a fully polynomial time approximation scheme (FPTAS) for this problem when the graph has bounded treewidth. |
