Quasi-Gap and Gap Functions for Non-Smooth Multi-Objective Semi-Infinite Optimization Problems

Atefeh Hassani Bafrani; Ali Sadeghieh

Volume 3, Issue 2 , January 2018, Pages 1-12

https://doi.org/10.30473/coam.2020.50781.1133

Abstract
  In this paper‎, ‎we introduce and study some new single-valued gap functions for non-differentiable semi-infinite multiobjective optimization problems with locally Lipschitz data‎. ‎Since one of the fundamental properties of gap function for optimization problems is its abilities in characterizing ...  Read More

A General Scalar-Valued Gap Function for Nonsmooth Multiobjective Semi-Infinite Programming

Ahmad Rezayi

Volume 3, Issue 2 , January 2018, Pages 13-26

https://doi.org/10.30473/coam.2019.45495.1110

Abstract
  For a nonsmooth multiobjective mathematical programming problem governed by infinitely many constraints‎, ‎we define a new gap function that generalizes the definitions of this concept in other articles‎. ‎Then‎, ‎we characterize the efficient‎, ‎weakly efficient‎, ...  Read More

MQ-Radial Basis Functions Center Nodes Selection with PROMETHEE Technique

Farhad Hadinejad; Saeed Kazem

Volume 3, Issue 2 , January 2018, Pages 27-47

https://doi.org/10.30473/coam.2019.46609.1117

Abstract
  In this paper‎, ‎we decide to select the best center nodes‎ ‎of radial basis functions by applying the Multiple Criteria Decision‎ ‎Making (MCDM) techniques‎. ‎Two methods based on radial basis‎ ‎functions to approximate the solution of partial differential‎ ‎equation ...  Read More

Characterization of Properly Efficient Solutions for Convex Multiobjective Programming with Nondifferentiable vanishing constraints

Javad Shaker Ardakani; shahriar Farahmand Rad; Nader Kanzi

Volume 3, Issue 2 , January 2018, Pages 49-58

https://doi.org/10.30473/coam.2019.42442.1094

Abstract
  This paper studies the convex multiobjective optimization problem with vanishing constraints‎. ‎We introduce a new constraint qualification for these problems‎, ‎and then a necessary optimality condition for properly efficient solutions is presented‎. ‎Finally by imposing some ...  Read More

Two Settings of the Dai-Liao Parameter Based on Modified Secant Equations

Saeed Nezhadhosein; Sahar Mohammadkhan Sartip

Volume 3, Issue 2 , January 2018, Pages 59-76

https://doi.org/10.30473/coam.2020.46435.1116

Abstract
  Following the setting of the Dai-Liao (DL) parameter in conjugate gradient (CG) methods‎, ‎we introduce two new parameters based on the modified secant equation proposed by Li et al‎. ‎(Comput‎. ‎Optim‎. ‎Appl‎. ‎202:523-539‎, ‎2007) with two approaches‎, ...  Read More

A Fully Fuzzy Method of Network Data Envelopment Analysis for Assessing Revenue Efficiency Based on Ranking Functions

Mohsen Rostamy-Malkhalifeh; Elham Poudineh; Ali Payan

Volume 3, Issue 2 , January 2018, Pages 77-96

https://doi.org/10.30473/coam.2019.46226.1115

Abstract
  The purpose of this paper is to evaluate the revenue efficiency in the fuzzy network data envelopment analysis‎. ‎Precision measurements in real-world data are not practically possible‎, ‎so assuming that data is crisp in solving problems is not a valid assumption‎. ‎One way to ...  Read More
