16. In the limit as the Filinov parameters α and β tend to infinity, the CFGA reduces to the standard Herman-Kluk expression for the autocorrelation function of a Gaussian initial wave packet. However, this expression can be difficult to converge by Monte Carlo and it is more efficient to use the cellularized method with large (but finite) Filinov parameters, so as to allow one to converge the approximation without loss of accuracy.
