| Abstract: | A nonlinear integer bilevel programming is well tackled by means of a new global optimization method proposed herein. The proposed method is performed within a two-level frame. The upper-level problem is first made continuity, and the continued problem is solved using the simulated annealing algorithm. On the other hand, given the information from the upper level, the lower level programming is easy solved after being changed into a non-constrained optimization problem and using a discrete searching technique. The resultant solution from the proposed method is the global optimum. The new method is demonstrated by a numerical example, with the solution satisfied and the method well verified. |
