An inexact proximal DC algorithm with sieving strategy for rank constrained least squares semidefinite programming

Mingcai Ding, Xiaoliang Song, Bo Yu

In this paper, the optimization problem of the supervised distance preserving projection (SDPP) for data dimension reduction (DR) is considered, which is equivalent to a rank const…

Mesh Independence of a Majorized ABCD Method for Sparse PDE-constrained Optimization Problems

Xiaoliang Song, Defeng Sun, Kim-Chuan Toh

A majorized accelerated block coordinate descent (mABCD) method in Hilbert space is analyzed to solve a sparse PDE-constrained optimization problem via its dual. The finite element…

A multi-level ADMM algorithm for elliptic PDE-constrained optimization problems

Xiaotong Chen, Xiaoliang Song, Zixuan Chen +1

In this paper, the elliptic PDE-constrained optimization problem with box constraints on the control is studied. To numerically solve the problem, we apply the 'optimize-discretize…

Task Embedded Coordinate Update: A Realizable Framework for Multivariate Non-convex Optimization

Yiyang Wang, Risheng Liu, Long Ma +1

We in this paper propose a realizable framework TECU, which embeds task-specific strategies into update schemes of coordinate descent, for optimizing multivariate non-convex proble…

An FE-dABCD algorithm for elliptic optimal control problems with constraints on the gradient of the state and control

Zixuan Chen, Xiaoliang Song, Bo Yu +1

In this paper, elliptic control problems with integral constraint on the gradient of the state and box constraints on the control are considered. The optimal conditions of the prob…
