الملخص العربي
Conjugate Gradient methods play an important role in solving unconstrained optimization, especially for large scale problems. In this paper, we compared the performance profile of the classical conjugate gradient coefficients FR, PRP with three new Ek . These three new Ek possess global convergence properties using the exact line search. Preliminary numerical results show that the three new Ek are very promising and efficient when compared to CG coefficients FR, PRP.
