Differentiable (F , ρ)-convex function of order 2 F -approximated vector optimization problem a b s t r a c t
In this paper, a new approximation method is introduced to characterize a so-called vector strict global minimizer of order 2 for a class of nonlinear differentiable multiobjective programming problems with (F , ρ)-convex functions of order 2. In this method, an equivalent vector optimization problem is constructed by a modification of both the objectives and the constraint functions in the original multiobjective programming problem at the given feasible point. In order to prove the equivalence between the original multiobjective programming problem and its associated F -approximated vector optimization problem, the suitable (F , ρ)-convexity of order 2 assumption is imposed on the functions constituting the considered vector optimization problem.
