"Note: The formulas show that the Hammersley set is actually the Halton sequence, but we get one more dimension for free by adding a linear sweep. This is only possible if N is known upfront. A linear set is also the set with lowest possible one-dimensional discrepancy in general. See more In mathematics, a low-discrepancy sequence is a sequence with the property that for all values of N, its subsequence x1, ..., xN has a low discrepancy. Roughly speaking, the discrepancy of a sequence is low if … See more The discrepancy of a set P = {x1, ..., xN} is defined, using Niederreiter's notation, as $${\displaystyle D_{N}(P)=\sup _{B\in J}\left {\frac {A(B;P)}{N}}-\lambda _{s}(B)\right }$$ where λs is the s-dimensional Lebesgue measure, … See more It is computationally hard to find the exact value of the discrepancy of large point sets. The Erdős–Turán–Koksma inequality provides an upper bound. Let x1,...,xN be points in I and H be an arbitrary positive integer. Then See more Quasirandom numbers have an advantage over pure random numbers in that they cover the domain of interest quickly and evenly. Two useful applications are in finding the characteristic function of a probability density function, … See more Let Ī be the s-dimensional unit cube, Ī = [0, 1] × ... × [0, 1]. Let f have bounded variation V(f) on Ī in the sense of Hardy and Krause.
