An algorithm to count, or alternatively generate, all k-element transversals of a set system is presented. For special cases it works in output-linear time.

The author describes a package for obtaining the vibrational modes of non-linear polyatomic molecules. The computed normal modes are visualized through Mathematica generated ...

The author discusses the fundamentals of plane hyperbolic geometry and describes a method for generating hyperbolic tilings by computer, based on the recently developed ...

This notebook illustrates how to use MathCode C++ to build a dynamic model of a physical system and then generate efficient code for simulation.

The WorldPlot packages provide a convenient way to create maps. From a database of country boundaries, colorful and informative geographic projections can be easily generated.

This package provides examples of utilities for working with external files. The function browse[n] generates a table of the files and subdirectories to depth n starting with ...

This notebook illustrates how to use MathCode F90 to build a dynamic model of a physical system and then generate efficient code for simulation.

A “3D” Mathematica-generated picture of monopoles and Dirac strings in $D=2+1$ compact QED is given. In the Villian approximation, the monopole part of the partition ...

This package provides tools for performing level-set simulations on complex terrain given a prescribed wind-field. Functions are also provided for generating two and three ...

This notebook gives a function for creating the points in a random walk in any Euclidean space with any number of points. An example is also given for generating a walk in ...
