Abstract. In this paper, we are interested in finding sufficient conditions, which ensure the existence of solutions to a weak (pessimistic) bilevel optimization problem in a topological sequential setting. To this aim, we consider an approach of by means of a family of regularized perturbed bilevel optimization problems of . Unlike , such problems have the privilege to admit solutions under mild assumptions. Using the notion of variational convergence, after establishing stability results, we prove the existence of solutions to problem .
