Item Convergence of a Two-parameter Family of Conjugate Gradient Methods with a Fixed Formula of Stepsize(Boletim da Sociedade Paranaense de Matemática., 2020) BOUAZIZ Khelifa; LASKRI Yamina (Co-Auteur)We prove the global convergence of a two-parameter family of conjugate gradient methods that use a new and different formula of stepsize from Wu [14]. Numerical results are presented to confirm the effectiveness of the proposed stepsizes by comparing with the stepsizes suggested by Sun and his colleagues [2,12].
