An adaptive descent extension of the Polak–Rebière–Polyak conjugate gradient method based on the concept of maximum magnification

Recently, a one-parameter extension of the Polak–Rebière–Polyak method has been suggested, having acceptable theoretical features and promising numerical behavior. Here, based on an eigenvalue analysis on the method with the aim of avoiding a search direction in the direction of the maximum magnific...
