Lagrange principle and necessary conditions
The present paper studies the following constrained vector optimization problem: , , , where , are locally Lipschitz functions, is function, and and are closed convex cones. Two types of solutions are important for the consideration, namely -minimizers (weakly efficient points) and -minimizers (isolated minimizers of order 1). In terms of the Dini directional derivative first-order necessary conditions for a point to be a -minimizer and first-order sufficient conditions for ...
