Optimizing a class of linear multi-step methods for the approximate solution of the radial Schrodinger equation and related problems with respect to phase-lag

摘要

In this paper we consider a methodology of optimization of the efficiency of a numerical method for the approximate solution of the radial Schrodinger equation and related problems. More specifically, we show how the methodology of vanishing of the phase-lag and its derivatives optimizes the behaviour of a numerical method.
