Random number generators

Several interfaces to external algorithms are provided in the core and CepGenAddOns libraries for the generation of random number according to some distributions of interests, and easily steerable through the randomGenerator sequential block (in Python cards). All modules are derived from a common cepgen::utils::RandomGenerator object, described below:

A full list of the algorithms and their parameters can be found here.
