Synthèse sur les résultats de convergence de quelques récentes méthodes du gradient conjugué non linéaires

Abstract

In this thesis we present a synthesis on the convergence results of some recent nonlinear conjugate gradient method namelly methods of JMG, LMY-DY and LMY-FR. All these variants generate descent directions and converge globally. Numerical simulations will be presented in order to illutrate the convergence of the methods cited aboved.
