On approximate quasi Pareto solutions in nonsmooth semi-infinite interval-valued vector optimization problems
Nguyen Huy Hung, Hoang Ngoc Tuan, Nguyen Van Tuyen
This paper deals with approximate solutions of a nonsmooth semi-infinite programming with multiple interval-valued objective functions. We first introduce four types of approximate…
Approximate solutions of interval-valued optimization problems
Nguyen Van Tuyen
This paper deals with approximate solutions of an optimization problem with interval-valued objective function. Four types of approximate solution concepts of the problem are propo…
Second-order optimality conditions for multiobjective optimization problems with constraints
Nguyen Quang Huy, Bui Trong Kien, Gue Myung Lee +1
In this paper, we introduce the second-order subdifferentials for functions which are Gâteaux differentiable on an open set and whose Gâteaux derivative mapping is locally Lipschit…
On second-order sufficient optimality conditions for vector optimization problems
Nguyen Van Tuyen, Jen-Chih Yao, Ching-Feng Wen +1
In this paper, we present some second-order sufficient conditions in terms of the Demyanov-Pevnyi's second-order directional derivatives for efficiency of vector optimization…
Second-order KKT optimality conditions for multi-objective optimal control problems
Bui Trong Kien, Nguyen Van Tuyen, Jen-Chih Yao
In this paper, we study second-order necessary and sufficient optimality conditions of Karush--Kuhn--Tucker-type for locally optimal solutions in the sense of Pareto to a class of…
