Alternating Proximal Point Algorithm with Gradient Descent and Ascent Steps for Convex-Concave Saddle-Point Problems
Hui Ouyang
Inspired by the Optimistic Gradient Ascent-Proximal Point Algorithm (OGAProx) proposed by Bo{ţ}, Csetnek, and Sedlmayer for solving a saddle-point problem associated with a convex-…
