Reformulations of multiobjective bilevel problems

Coauthors: Konstantinos Kaparis, Huifu Xu


We present new approaches for multiobjective bilevel optimization, derived from an optimality condition for the lower level problem that leads naturally to a nonsmooth equality constraint. The nonsmoothness of the new constraint stems from its derivation as an optimal value function of a particular direction search problem. Preliminary numerical results on bilevel problems occuring in electricity markets show
the efficacy of the approach. Further, we consider possible extensions to the multilevel case.
