An Augmented Lagrangian Primal-Dual Semismooth Newton Method for Multi-Block Composite Optimization

Zhanwang Deng, Kangkang Deng, Jiang Hu +1

In this paper, we develop a novel primal-dual semismooth Newton method for solving linearly constrained multi-block convex composite optimization problems. First, a differentiable…
