An inexact -order regularized proximal Newton method for nonconvex composite optimization
Ruyu Liu, Shaohua Pan, Yitian Qian
This paper concerns the composite problem of minimizing the sum of a twice continuously differentiable function and a nonsmooth convex function. For this class of nonconvex and…

A VMiPG method for composite optimization with nonsmooth term having no closed-form proximal mapping
Taiwei Zhang, Shaohua Pan, Ruyu Liu
This paper concerns the minimization of the sum of a twice continuously differentiable function and a nonsmooth convex function without closed-form proximal mapping. For th…

An inexact LPA for DC composite optimization and application to matrix completions with outliers
Ting Tao, Ruyu Liu, Shaohua Pan
This paper concerns a class of DC composite optimization problems which, as an extension of convex composite optimization problems and DC programs with nonsmooth components, often…
