Class ProductConstraint

java.lang.Object
  de.jstacs.sequenceScores.differentiable.logistic.ProductConstraint

All Implemented Interfaces:

LogisticConstraint, Storable, Cloneable

public class ProductConstraint
extends Object
implements LogisticConstraint

This class implements product constraints, i.e., the method getValue(Sequence,int) returns the product of the values for the positions defined in the constructor.
