The Convergence of a Smoothing Method for the Mixed Complementarity Problem |
|
|
Abstract:We converted the mixed complementarity problem into a system of nonsmooth nonlinear equations by using Fischer-Burmeister function,and we used a smooth function to approximate the Fischer Burmeister function. By combining trust region method with gradient method, a Jacobian smoothing method was proposed. Under some conditions, we proved the global convergence and local convergence of the algorithm. Numerical result indicates that the algorithm is quite promising. |
