Xian Jun Long, Jing Quan, Dao-Jun Wen · Bulletin of the Korean Mathematical Society · 2013
The purpose of this paper is to establish some relationships between proper efficiency of set-valued optimization problems and proper efficiency of vector variational-like inequalities under the assumptions of generalized cone-preinvexity. Our results extend and improve the corresponding results in the literature.
