Practical Calculation Scheme for Generalized Seniority

Abstract

We propose a scheme or procedure for doing practical calculations with generalized seniority. It reduces the total computing time by calculating and storing in advance a set of intermediate quantities, taking advantage of the memory capability of modern computers. The requirements and performance of the algorithm are analyzed in detail.
