Efficiency

The study of second-order optimality conditions is one of the most important topics in optimization theory and attracting the attention and interest of many authors. In this paper, we introduce a novel solution concept called “essential local efficient solutions of second-order” for nonconvex constrained multiobjective optimization problems.
