A smooth Levenberg-Marquardt method without nonsingularity condition for wLCP

open access: yesAIMS Mathematics, 2022
In this paper we consider the weighted Linear Complementarity Problem (wLCP). By using a smooth weighted complementarity function, we reformulate the wLCP as a smooth nonlinear equation and propose a Levenberg-Marquardt method to solve it.

Local convergence of the Levenberg-Marquardt method under H\"{o}lder metric subregularity [PDF]

open access: yes, 2019
We describe and analyse Levenberg-Marquardt methods for solving systems of nonlinear equations. More specifically, we propose an adaptive formula for the Levenberg-Marquardt parameter and analyse the local convergence of the method under H\"{o}lder ...
