Abstract EN
In this paper, a new formula of ?? is suggested for the conjugate gradient method of solving unconstrained optimization problems based on three terms and step size of cubic.
Our new proposed CG method has descent condition, sufficient descent condition, conjugacy condition, and global convergence properties.
Numerical comparisons with two standard conjugate gradient algorithms show that this algorithm is very effective depending on the number of iterations and the number of functions evaluated.
