Fatemeh Gorgini Shabankareh; Nader Kanzi; Javad Izadi; Kamal Fallahi

Volume 6, Issue 2 , July 2021, , Pages 23-35

https://doi.org/10.30473/coam.2021.60747.1176

Abstract
  In this paper‎, ‎some constraint qualifications ‎of‎ the Guignard type are defined for optimization problems with continuously differentiable objective functions and locally Lipschitz switching constraints‎. ‎Then‎, ‎a new type of stationary condition‎, ‎named ...  Read More

Topological Subdifferential and its Role in Nonsmooth Optimization with Quasiconvex Data

Hamed Soroush

Volume 5, Issue 2 , July 2020, , Pages 83-91

https://doi.org/10.30473/coam.2021.59584.1165

Abstract
  In this paper‎, ‎we study nonsmooth optimization problems with quasiconvex functions using topological subdifferential‎. ‎We present some necessary and sufficient optimality conditions and characterize topological pseudoconvex functions‎. ‎Finally‎, ‎the Mond-Weir type ...  Read More

Necessary Optimality Conditions for Non-smooth Continuous-Time Problems‎ ‎Using Convexificators

Ali Ansari Ardali

Volume 5, Issue 1 , January 2020, , Pages 1-13

https://doi.org/10.30473/coam.2021.56443.1154

Abstract
  In this paper, ‎we develop general necessary optimality conditions of the KKT types for non-smooth continuous-time optimization problems with inequality constraints‎. ‎The primary instrument in our study is the concept of a convexificator‎. ‎Based on this concept‎, ‎non-smooth ...  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
