WebSep 30, 2015 · These algorithms are based on a Gaussian noise, least-squares model, simplifying the Langley and Fitch's (1974) Poisson model implemented in the r8s package ( Sanderson 2003). We showed that this model should be robust to uncorrelated violations of the molecular clock, and our simulation results confirm this theoretical prediction.

The speed of this algorithm will thus rise as the fourth power of the number of species, rather than as the third power as do most of the others. Hence it is expected to get very slow as the number of species is made larger.
