Comparative study of several classical and modified conjugate gradient using inexact line search / Uzir Ibrahim

Conjugate gradient (CG) method is one of the method in finding minimization or maximization of objective function to solve unconstrained optimization problems. Many studies have been conducted recently to improve this method but some of the modified CG seem to be more difficult and complicated than...
