Abstract

This paper presents a new hybrid conjugate gradient method, combining the Conjugate Descent (CD) and Al-Bayati & Al-Assady (BA) methods, for solving unconstrained optimization problems. We provide a convergence analysis of the proposed method and demonstrate its effectiveness through numerical examples.
