It is found that a proposed random number generator r an2, recently presented in the Numerical Recipes column [W. H. Press and S. A. Teukolsky, Comput. Phys. 6, 521-524 (1992)], is a good one, but aâ€¦ (More)

Binary matrices originating from presence/absence data on species (rows) distributed over sites (columns) have been a subject of much controversy in ecological biogeography. Under the null hypothesisâ€¦ (More)

The cutting corners algorithm can be used to generate random numbers from any unimodal density which is speciied only as a computer subroutine. This allows for a single program that can generateâ€¦ (More)

Evaluating an extremely useful graph property, the spectral radius (largest absolute eigenvalue of the graph adjacency matrix), for large graphs requires excessive computing resources. This problemâ€¦ (More)

For differential-difference equations, we provide a method that gives numerical solutions accurate to hundreds or even thousands of digits. We illustrate with numerical solutions to three classicalâ€¦ (More)
