Variants of alternating minimization method with sublinear rates of convergence for convex optimization
Hui Zhang, Lizhi Cheng
The alternating minimization (AM) method is a fundamental method for minimizing convex functions whose variable consists of two blocks. How to efficiently solve each subproblems wh…

Projected shrinkage algorithm for box-constrained L1-minimization
Hui Zhang, Lizhi Cheng
Box-constrained L1-minimization can perform remarkably better than classical L1-minimization when correction box constraints are available. And also many practical L1-minimization…

Proximal linearized iteratively reweighted least squares for a class of nonconvex and nonsmooth problems
Hui Zhang, Tao Sun, Lizhi Cheng
For solving a wide class of nonconvex and nonsmooth problems, we propose a proximal linearized iteratively reweighted least squares (PL-IRLS) algorithm. We first approximate the or…
