A low-discrepancy sequence is such that its discrepancy decays asymptotically at least as fast as [OMICRON]([(log N).
Many other constructions of low-discrepancy sequences are known [9, 10, 15, 34], but they are more complicated to generate [19], and they play a significant role only when the number of dimensions is much larger than what we consider here.
Due to issues related to the speed of convergence, low-discrepancy sequences often can be used in place of either random (or pseudo-random) sampling, since they converge more quickly and can provide more even coverage of a distribution.
