New Three-Term Conjugate Gradient Method Based On Wfr Variant With Practical Applications / Soheyb Laib  

Public ISBD Titre : New Three-Term Conjugate Gradient Method Based On Wfr Variant With Practical Applications Type de document : document électronique Auteurs : Soheyb Laib, Auteur ; Tahar Labidi, Auteur ; Khelladi ,Samia, Directeur de thèse Editeur : Sétif:UFS Année de publication : 2026 Importance : 1 vol (58 f.) Format : 29 cm Note générale : Langues : Anglais (eng) Catégories : Mathématique Mots-clés : Nonlinear unconstrained optimization, Conjugate gradient method, Descent direction, Global convergence, Inexact line search. Résumé : The conjugate gradient method is widely used for large-scale unconstrained optimization due to its efficiency in iteration number and computing time. In this dissertation, we propose a new three-term conjugate gradient method inspired from the Fletcher–Reeves approach, where we introduce a novel descent direction. We conduct the numerical experiments on classical unconstrained optimization problems and on practical applications including the image restoration and sparse signal recovery problems. The results confirm the efficiency and robustness of the proposed approach compared to some existing algorithms.
