Bolintinéanu Faculté des Sciences, IREMIA, Université de La Réunion, 97715 Saint Denis, France The aim of this paper is to present several versions of vector variational principles related to some type of metrically consistent ε-efficiency and to the approximate necessary first order efficiency condition. Keywords: Vector optimization, multicriteria optimization, epsilon-efficiency, stationary sequences, Kuhn-Tucker-sequences, minimizing sequences, Pareto optimizing sequences, weakly efficient sequences, convex analysis, variational analysis, Ekeland variational pri [ Fulltext-pdf (384 KB)] |
