First-Order Methods for Solving Convex (Strongly) Concave Minimax Problems with Functional Constraints

Yangyang Xu, Xinhao Ying

Minimax problems arise in many applications, including robust learning and Stackelberg models. Most existing methods for minimax problems address unconstrained or projection-friend…
