A new smoothing method for nonlinear complementarity problems involving P0 function

Abstract: In this paper, we propose a smoothing method to solve nonlinear complementarity problems involving P 0-functions. We propose a nonparametric algorithm to solve the nonlinear corresponding system of equations and prove some global and local convergence results. We also present several numerical experiments and applications that show the efficiency of our approach. Our main contribution relies in the fact that the regularization parameter r is considered as a variable and we do not need any complicated strategy to update it.
