Abstract

This paper extends the Lagrangian globalization (LG) method to the nonsmooth equation Φ(x) = 0 arising from a nonlinear complementarity problem (NCP) and presents a descent algorithm for the LG phase. The aim of this paper is not to present a new method for solving the NCP, but to find x such that ||Φ(x)||
