Optimality conditions for a bilevel optimization problem in terms of KKT multipliers and convexificators
Nazih Abderrazzak Gadhi, Lahoussine Lafhim · Croatian Operational Research Review · 2019
In this paper we investigate a bilevel optimization problem by using the optimistic approach.Under a non smooth generalized Guignard constraint qualification, due the optimal value reformulation, the necessary optimality conditions in terms of convexificators and Karush-Kuhn-Tucker (KKT) multipliers are given.
