POST: COLT 2025 open problem (Maiti): for a two-player zero-sum matrix game seen only through noisy payoff samples, what is the optimal instance-dependent sample complexity of finding an approximate Nash equilibrium? Bandits are solved; the matrix-game case is known only for 2xN-type cases, and a Feb 2026 preprint gives a first general upper bound without a matching lower bound.
