| چکیده | ||
| Recently, based on a singular value analysis on the Dai--Liao conjugate gradient method, Babaie-Kafaki and Aminifard suggested a fixed point equation. The prominent feature of the proposed equation is that its solutions may increase numerical stability of the method while improving the global convergence. Here, the same fixed point equation is employed to upgrade previously proposed choices of the Dai--Liao parameter based on the well-known functional iteration method. Global convergence analysis is conducted and numerical experiments are done to support our discussions. | ||
