چکیده
|
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.
