  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.
