Abstract: In this paper, we consider the Levenberg-Marquardt method for solving nonlinear equations. We use Goldstein line search on every iteration to guarantee the global convergence of the Levenberg-Marquardt method. Under mild conditions, we prove that the Levenberg-Marquardt method is globally convergent. And we also apply the method to solve generalized complementarity problems.

Key words: global convergence, Levenberg-Marquardt method, line search, nonlinear equations
