Efficient computation of addition-subtraction chains using generalized continued Fractions
Amadou Tall and Ali Yassin Sanghare
Abstract: The aim of this paper is to present a new way of computing short addition-subtraction chains using the generalized continued fractions where subtraction is allowed. We will recover the most used ways of getting addition-subtraction chains. This method is not always optimal but gives minimal chains that are easy to compute.
