On best proximity point of ψ-Geraghty contractions

open access: yes, 2013
Very recently, Caballero, Harjani and Sadarangani (Fixed Point Theory Appl. 2012:231, 2012) observed some best proximity point results for Geraghty contractions by using the P-property.

A combined first and second order model for a junction with ramp buffer [PDF]

open access: yesSMAI Journal of Computational Mathematics, 2019
Second order macroscopic traffic flow models are able to reproduce the so-called capacity drop effect, i.e., the phenomenon that the outflow of a congested region is substantially lower than the maximum achievable flow.

Sensitivity analysis for parametric vector optimization problems using differential equations approach

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 25, Issue 9, Page 621-628, 2001., 2001
A new method for obtaining sensitivity information for parametric vector optimization problems (VOP) v is presented, where the parameters in the objective functions and anywhere in the constraints. This method depends on using differential equations technique for solving multiobjective nonlinear programing problems which is very effective in finding ...

A modification of the αBB method for box-constrained optimization and an application to inverse kinematics

open access: yesEURO Journal on Computational Optimization, 2016
For many practical applications it is important to determine not only a numerical approximation of one but a representation of the whole set of globally optimal solutions of a non-convex optimization problem.

An economic order quantity model with reverse logistics program

open access: yesOperations Research Perspectives, 2020
The economic order quantity (EOQ) model has evolved greatly over past decades on the strength of incorporating realistic factors. In recent times, interest has been geared towards studying the effect of reverse flow of products into inventory system.

Best proximity point theorems for multivalued mappings on partially ordered metric spaces

open access: yes, 2016
In this paper, we prove some best proximity point theorems for multivalued mappings in the setting of complete partially ordered metric spaces. As an application, we infer best proximity point and fixed point results for single valued mappings in ...

A remark on Gwinner′s existence theorem on variational inequality problem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 8, Page 573-575, 2000., 2000
Gwinner (1981) proved an existence theorem for a variational inequality problem involving an upper semicontinuous multifunction with compact convex values. The aim of this paper is to solve this problem for a multifunction with open inverse values.

Numerical construction of structured matrices with given eigenvalues

open access: yesSpecial Matrices, 2019
We consider a structured inverse eigenvalue problem in which the eigenvalues of a real symmetric matrix are specified and selected entries may be constrained to take specific numerical values or to be nonzero.

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.

A New Filled Function for Global Optimization

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
The filled function method has recently become very popular in optimization theory, as it is an e cient and e ective method for finding the global minimizer of multimodal functions.
