Detailed Description

Description of the class THaltonSequence.

Description

(source Numerical Recipes - Chapter 7-7 page 309)

In one dimension, the jth number $ H_j$ in the sequence is obtained by the followings steps :
  • Write $ j$ as a number in base $ b$, where $ b$ is some prime. For example, $ j=17$ in base $ b=3$ is 122.
  • Reverse the digits and put a radix point (i.e. a decimal point base $ b$) in front of the sequence. In our example, we get 0.221 base 3. It is the result $ H_j$.
To get a sequence of n-tuples in n-space, you make each component a Halton sequence with a different prime base $ b$. Typically, we can use the n primes.

Implementation

The code original is in the library seq_beta_04.21.01 de Duchemol and co
