HALTON
The Halton Quasi Monte Carlo (QMC) Sequence


HALTON is a C++ library which computes elements of a Halton Quasi Monte Carlo (QMC) sequence using a simple interface.

A more sophisticated library is available in HALTON_ADVANCED, but I find this simple version to be preferable for everyday use!

The standard M-dimensional Halton sequence is simply composed of M 1-dimensional van der Corput sequences, using as bases the first M primes.

The HALTON function will return the M-dimensional element of this sequence with index I.

The HALTON_SEQUENCE function will return the M-dimensional elements of this sequence with indices I1 through I2.

The HALTON_INVERSE function accepts an M-dimensional value, presumably computed by HALTON, and returns its original index I.

The HALTON_BASE function allows the user to replace the standard basis of primes with some other choice.
