Description
In this paper, we proposed a matrix-free double-search direction based on the
updated parameter file of the double-search direction with a new
mathematical formula for the gamma parameter. When comparing the
numerical results of this algorithm with the standard (HWY) algorithm which
given by Halilu, Waziri and Yusuf in 2020. We get very robust numerical
results. The proposed algorithm is devoid of derivatives to solve large-scale
non-linear problems by combining two search directions in one search
direction. We demonstrated the overall convergence of the proposed
algorithm under certain conditions. The numerical results presented in this
paper show that the new search direction is useful for solving widespread
non-linear test problems.
