Abstract

A new step-size rule is proposed for the conjugate gradient method. The method uses a unified formula for obtaining step-size which does not involve any matrix operation or function evaluations. Numerical results obtained are graphically illustrated using performance profiling software showed that the new formula perform better in terms of computational efforts and execution time compared to an existing formula for obtaining the step-size.
