In this paper, we study a pessimistic bilevel programming problem in which the set of solutions of the lower level problem is discrete. We first transform such a problem into a single-level optimization problem by using the maximum-entropy techniques. We then present a maximum entropy approach for solving the pessimistic bilevel programming problem. Finally, two examples illustrate the feasibility of the proposed approach.
