Researchers have developed a new first-order optimization method designed to tackle complex nonconvex-nonconcave minimax problems. This method addresses challenges posed by a local Kurdyka-Lojasiewicz (KL) condition, which is less restrictive than previous assumptions but introduces analytical difficulties as algorithms approach stationary points. The proposed inexact proximal gradient method leverages the generalized Hölder smoothness of the associated maximal function to provide complexity guarantees for finding approximate stationary points.
