Which Nash Equilibrium? Solver-Dependent Selection on Zero-Sum Nash Polytopes
Reported by arXiv cs.AI: Which Nash Equilibrium? Solver-Dependent Selection on Zero-Sum Nash Polytopes. Analysis and context written by TickrWire.
Research paper reveals that different Nash equilibrium solvers converge to distinct equilibria in zero-sum games, challenging the assumption of solver interchangeability.
Many two-player zero-sum games admit not a unique Nash equilibrium but a convex set of them: a polytope of profiles that all share the minimax value V* yet prescribe different behaviour. Standard solvers each converge to some equilibrium and are treated as interchangeable. We ask whether they instead select different members of the Nash set, systematically as a function of the algorithm rather than the seed. Using a tabular, exactly solvable testbed of six games with analytically known Nash sets -- including a two-dimensional Nash polytope and Kuhn poker -- we find that (i) selection is determ
