A convex combination based primal-dual algorithm with linesearch for general convex-concave saddle point problems
Xiaokai Chang, Junfeng Yang, Hongchao Zhang
Using convex combination and linesearch techniques, we introduce a novel primal-dual algorithm for solving structured convex-concave saddle point problems with a generic smooth non…
