On the existence and the stability of solutions in nonconvex vector optimization
Tran Van Nghi, Le Ngoc Kien, Nguyen Van Tuyen
The paper is devoted to the existence of weak Pareto solutions and the weak sharp minima at infinity property for a general class of constrained nonconvex vector optimization probl…
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…
Lipschitz continuity of solutions and corresponding multipliers to distributed and boundary semilinear elliptic optimal control problems with mixed pointwise control-state constraints
Vu Huu Nhu, Nguyen Quoc Tuan, Nguyen Bang Giang +1
This paper is concerned with the existence and regularity of mininizers as well as of corresponding multipliers to an optimal control problem governed by semilinear elliptic equati…
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…
Optimality conditions for approximate Pareto solutions of a nonsmooth vector optimization problem with an infinite number of constraints
Ta Quang Son, Nguyen Van Tuyen, Ching-Feng Wen
In this paper, we present some new necessary and sufficient optimality conditions in terms of the Clarke subdifferentials for approximate Pareto solutions of a nonsmooth vector opt…
A note on approximate Karush-Kuhn-Tucker conditions in locally Lipschitz multiobjective optimization
Nguyen Van Tuyen, Jen-Chih Yao, Ching-Feng Wen
In the recent paper of Giorgi, Jiménez and Novo (J Optim Theory Appl 171:70--89, 2016), the authors introduced the so-called approximate Karush-Kuhn-Tucker (AKKT) condition for smo…
