java.lang.Object
de.jstacs.utils.random.MultivariateRandomGenerator
de.jstacs.utils.random.SoftOneOfN
public class SoftOneOfN
- extends MultivariateRandomGenerator
This random generator returns 1-epsilon for one and equal parts for
the rest. The content of container MRGParams is never used in this class.
