Metrically well-set minimization problems
TL;DR: In this paper, the concept of well-posedness was introduced for convex minimization problems on metric spaces, generalizing the notion due to Tykhonov to situations in which there is no uniqueness of solutions.
Book ChapterDOI
Well Posedness of Vector Optimization Problems
TL;DR: In this paper, the authors investigated upper semicontinuity of solutions in parametric vector optimization problems without any compactness assumptions of feasible solution sets and distinguished a class of well posed problems for which sufficient conditions for upper semiconvolution of solutions are formulated without any standard compactness assumption.
Journal ArticleDOI
Vector variational principle
TL;DR: In this paper, an Ekeland variational principle for monotonically semicontinuous mappings with perturbations given by a convex bounded subset of directions multiplied by the distance function was proved.
Journal Article
Contingent epiderivative and its applications to set-valued optimization
Ewa M. Bednarczuk,Wen Song +1 more
TL;DR: In this article, the authors give an alternative definition of contingent epiderivative for a set-valued map, which is used to define necessary and/or sufficient optimal conditions for setvalued optimization problems and study sensitivity of a family of parametrized vector optimization problems.
