[jira] [Updated] (MATH-826) RFE: low discrepancy sequence generator

["Thomas Neidhart (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/MATH-826?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Neidhart updated MATH-826:
---------------------------------

    Attachment: SobolSequenceRandomGenerator.java

First draft of a random generator based on a Sobol sequence.

The user can select the dimension when creating the generator. Thus when a user is interested in 3d points, 3 generators are needed.

The generator includes direction numbers from [http://web.maths.unsw.edu.au/~fkuo/sobol/] for the first 100 dimensions (they are under BSD license), but custom ones can be provided.

Does this make sense?

> Please provide a low discrepancy sequence random number generator.

> Support for such a generator is poor in Java and existing implementations tend to be standalone and do not provide a user friendly API. Ideally, such a generator would implement Random, but using the Apache Commons Math random API would be acceptable.
