Abstract
The evaluation of slowly convergent continued fractions α1/(β1+α2/(β2+...)) can be made more efficient by replacing an approximant α1/(β1+α2/(β2+...+αr/βr)) by a modified approximant α1/(β1+α2/(β2+...+αr/(βr+ωr))), according to work done by Thron, Waadeland and Jacobsen. The convergence factor should of course be a reasonably good approximation to the tail αr+1/(βr+1+...).
