Quadratic Programming Approach for Nash Equilibrium Computation in Multiplayer Imperfect-Information Games
arXiv:2509.25618v2 Announce Type: replace-cross Abstract: There has been significant recent progress in algorithms for approximation of Nash equilibrium in large two-player zero-sum imperfect-information games and exact computation of Nash equilibrium in multiplayer strategic-form games. While counterfactual regret minimization and fictitious play are scalable to large games and have convergence guarantees in two-player zero-sum games, they do not guarantee convergence to Nash equilibrium in multiplayer games. We present an approach for exact computation of Nash equilibrium in multiplayer impe
The paper addresses a known limitation in current AI algorithms for multiplayer games, specifically the lack of guaranteed convergence to Nash equilibrium, suggesting a timely mathematical and algorithmic advancement.
