About

n-dimensional low-discrepancy sequence generators/iterators.

This package provides the following n-dimensional low-discrepancy sequence generators, partially based on the article The Unreasonable Effectiveness of Quasirandom Sequences by Martin Roberts.

Halton

Configurable basis for each dimension:

haltonND([2,3])

Kronecker

Configurable basis for each dimension:

kroneckerND([1 / 2 ** 0.5, 1 / 5 ** 0.5])

R₂ recurrence

Based on Kronecker with each dimension's base automatically derived from the Plastic number:

plasticND(2)

Status

BETA - possibly breaking changes forthcoming
