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 x̂ such that ∥Φ(x̂)∥ < ∥Φ(x̄)∥ when the NCP has a solution and x̄ is a stationary point but not a solution.
