■The Harder Path: Last Iterate Convergence for Uncoupled Learning in Zero-Sum Games with Bandit Feedback

Authors	Côme Fiegel (ENSAE), Pierre Menard (Meta), Tadashi Kozuno, Michal Valko (INRIA), Vianney Perchet (ENSAE)
Research Introduction	We study learning in repeated zero-sum matrix games under the uncoupled bandit feedback setting, where players cannot communicate and observe only their own rewards and actions. We theoretically demonstrate that guaranteeing last-iterate convergence to a Nash equilibrium comes at a significant cost: the best achievable convergence rate is O(1/T^0.25), which is substantially slower than the standard O(1/T^0.5) rate for average-iterate convergence. We then propose two algorithms that achieve this optimal rate up to constant and logarithmic factors.
