Good permutations for deterministic scrambled Halton …

One of the most prominent solutions is the scrambled Halton sequence, which uses permutations of the coefficients used in the construction of the standard sequence. Another solution is the leaped Halton, which skips points in the standard sequence. See more In statistics, Halton sequences are sequences used to generate points in space for numerical methods such as Monte Carlo simulations. Although these sequences are deterministic, they are of low discrepancy, … See more • Constructions of low-discrepancy sequences See more The Halton sequence is constructed according to a deterministic method that uses coprime numbers as its bases. As a simple example, let's … See more WebTo ameliorate the poor coverage of Halton draws for higher dimensions, researchers have adopted modified procedures such as shuffled and scrambled Halton draws. Hess and Polak (2003a, 2003b) describe the construction of the shuffled sequence, which creates multi-dimensional sequences from randomly shuffled versions of the one- Webps = scramble(p,type) returns a scrambled copy ps of the point set p, created using the scramble type specified by type.
