Abstract
A four-term CG-method based on pure conjugacy condition are proposed, Research
activities on extending three-term CG-method to the four-term conjugate gradient method.
The new method shown that the suggested CG-methods owns the sufficient descent
property. The global convergence of the proposed scheme with the general Wolfe conditions
under a suitable assumption was verified. Finally, the computational experiment show that
the new method is efficient and robust.
