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 ...

Convergence of Peaceman-Rachford splitting method with Bregman distance for three-block nonconvex nonseparable optimization

open access: yesDemonstratio Mathematica
It is of strong theoretical significance and application prospects to explore three-block nonconvex optimization with nonseparable structure, which are often modeled for many problems in machine learning, statistics, and image and signal processing.

Algorithms Based on Unions of Nonexpansive Maps

open access: yes, 2018
In this note, we consider a framework for the analysis of iterative algorithms which can described in terms of a structured set-valued operator. More precisely, at each point in the ambient space, we assume that the value of operator can be expressed as ...

GLOBAL OPTIMIZATION APPROACH TO UTILITY MAXIMIZATION PROBLEM

open access: yes, 2015
We consider the utility maximization problem for oligopsonistic market which is nonconvex optimization problem. Unlike the utility maximization for competitive market, the problem belongs to a class of global optimization. The purpose of this paper is to

Best proximity point theorems for reckoning optimal approximate solutions

open access: yes, 2012
Given a non-self mapping from A to B, where A and B are subsets of a metric space, in order to compute an optimal approximate solution of the equation Sx=x, a best proximity point theorem probes into the global minimization of the error function x⟶d(x,Sx)

GLOBAL CONVERGENCE OF THE TMR METHOD FOR UNCONSTRAINED OPTIMIZATION PROBLEMS

open access: yes, 2017
Conjugate gradient methods are probably the most famous iterative methods for solving large scale optimization problems in scientific and engineering computation, characterized by the simplicity of their iteration and their low memory requirements. It is
