Researchers have developed a finite-sample analysis for decentralized learning algorithms in two-player zero-sum stochastic games. The proposed methods, including a payoff-based algorithm for matrix games and a value iteration with smoothed best response (VI-SBR) for stochastic games, aim to find epsilon-Nash distributions and equilibria. The analysis establishes sample complexity guarantees, with the VI-SBR algorithm achieving a sample complexity of \tilde{\mathcal{O}}(\epsilon^{-8}) for finding an \epsilon-Nash equilibrium in stochastic games. The technical approach utilizes a coupled Lyapunov-drift framework to handle complex iterative algorithms and nonstationary sampling processes. AI
