An ADMM-based heuristic algorithm for optimization problems over nonconvex second-order cone

open access: yesOpen Computer Science
The nonconvex second-order cone (nonconvex SOC) is a nonconvex extension to the convex second-order cone, in the sense that it consists of any vector divided into two sub-vectors for which the Euclidean norm of the first sub-vector is at least as large ...

A new branch and bound algorithm for minimax ratios problems

open access: yesOpen Mathematics, 2017
This study presents an efficient branch and bound algorithm for globally solving the minimax fractional programming problem (MFP). By introducing an auxiliary variable, an equivalent problem is firstly constructed and the convex relaxation programming ...

A class of null space conditions for sparse recovery via nonconvex, non-separable minimizations

open access: yesResults in Applied Mathematics, 2019
For the problem of sparse recovery, it is widely accepted that nonconvex minimizations are better than ℓ1 penalty in enhancing the sparsity of solution.

Solution for the system of generalized nonlinear mixed variational inequality problems

open access: yesDemonstratio Mathematica
We propose in this paper a class of generalized nonlinear mixed variational inequality problems on Banach spaces, which is composed of three elliptic generalized nonlinear mixed variational inequality problems.

Sufficient pruning conditions for MINLP in gas network design

open access: yesEURO Journal on Computational Optimization, 2017
One-quarter of Europe’s energy demand is provided by natural gas distributed through a vast pipeline network covering the whole of Europe. At a cost of 1 million Euros per kilometer the extension of the European pipeline network is already a multi ...

An inertial forward–backward algorithm for the minimization of the sum of two nonconvex functions

open access: yesEURO Journal on Computational Optimization, 2016
We propose a forward–backward proximal-type algorithm with inertial/memory effects for minimizing the sum of a nonsmooth function with a smooth one in the nonconvex setting.
