δ-perturbation of bilevel optimization problems : an error bound analysis

Antoniou, Margarita; Sinha, Ankur; Papa, Gregor - In: Operations research perspectives 13 (2024), pp. 1-19

In this paper, we analyze a perturbed formulation of bilevel optimization problems, which we refer to as δ-perturbed formulation. The δ-perturbed formulation allows to handle the lower level optimization problem efficiently when there are multiple lower level optimal solutions. By using an...
