An entropy function method for mathematical programs with equilibrium constraints |
| |
| Abstract: | An entropy function method for solving mathematical programs with equilibrium constraints (MPEC) is proposed in this paper.Based on reformulating the original MPEC into a one|level nonsmooth optimization problem by using the entropy function approximation,a sequential smooth constrained minimization method for solving MPECs is presented.Under the condition that the variational inequality constraint is strongly monotone,the existence of the solution to the approximating smooth constrained minimization problem is proved and the global convergence of the method is obtained.Some numerical results are presented. |
