| Abstract: | In this paper, the authors present an s-dependent conjugate gradient method for unconstrained optimization problem and make two different kinds of estimations of upper bounds of β k with respect to (beta_{k}^{mathrm{FR}}) which are called dependent ratio. The global convergence of s-dependent GFR conjugate gradient method using several step-size rules is obtained. |
