New single-loop algorithm matches multi-loop complexity in optimization

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a novel single-loop algorithmic framework designed for smooth nonconvex--concave minimax optimization. This new method, termed the projected damped extragradient method, integrates projected extragradient updates, dual momentum, and a moving proximal center. It achieves the best-known complexity for both optimization-stationarity and game-stationarity criteria among single-loop first-order methods, matching the performance of multi-loop approaches. AI
