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...

Approximate values for mathematical programs with variational inequality constraints

Lignola, M.; Morgan, Jacqueline - In: Computational Optimization and Applications 53 (2012) 2, pp. 485-503

In general the infimal value of a mathematical program with variational inequality constraints (MPVI) is not stable under perturbations in the sense that the sequence of infimal values for the perturbed programs may not converge to the infimal value of the original problem even in presence of...
