ldsgen::HaltonN class

#include <ldsgen/lds_n.hpp>

Halton(n) sequence generator.

The HaltonN class is a sequence generator that generates points in a N-dimensional space using the Halton sequence. The Halton sequence is a low-discrepancy sequence that is commonly used in quasi-Monte Carlo methods. It is generated by iterating over two different bases and calculating the fractional parts of the numbers in those bases. The HaltonN class keeps track of the current count and bases, and provides a pop() method that returns the next point in the sequence as a std::vector<double>.

*     HaltonN([2,3,5]) sequence (3D):
*     pop() -> [0.5, 0.333, 0.2]    (VdC bases [2,3,5])
*     pop() -> [0.25, 0.666, 0.4]   (next in each sequence)
*     pop() -> [0.75, 0.111, 0.6]   (etc...)
*     ...
