WebOct 2, 2016 · halton, a Python code which computes elements of a Halton Quasi Monte Carlo (QMC) sequence using a simple interface. The standard M-dimensional Halton sequence is simply composed of M 1-dimensional van der Corput sequences, using as bases the first M primes. WebQuasi-random sequences are functions from the positive integers to the unit hypercube. To be useful in application, an initial point set of a sequence must be generated. Point sets are matrices of size n-by-d, where n is the number of points and d is the dimension of the hypercube being sampled. The functions haltonset and sobolset construct point sets with …

WebHalton sequences are best understood through an example. Start with a number that defines the sequence. For illustration, consider the number 3. A Halton sequence for number 3 is constructed as follows. Take the unit interval (0,1) and divide it into 3 parts. The dividing points become the first two elements of the Halton sequence: 1/3 and 2/3. WebReturns a sample from the dim dimensional Halton sequence.
