Relaxed Proximal Point Algorithm: Tight Complexity Bounds and Acceleration without Momentum
Bofan Wang, Shiqian Ma, Junfeng Yang +1
In this paper, we focus on the relaxed proximal point algorithm (RPPA) for solving convex (possibly nonsmooth) optimization problems. We conduct a comprehensive study on three type…
