Description

Interface Summary

MappingDouble

Class Summary

ASCII_CharStream	An implementation of interface CharStream, where the stream is assumed to contain only ASCII characters (without unicode processing).
ASCII_UCodeESC_CharStream	An implementation of interface CharStream, where the stream is assumed to contain only ASCII characters (with java-like unicode escape processing).
BayesClassifier	Implementation of Bayesian Network Classifiers.
BayesInterchangeFormat
BayesNet
Bracketing	Perform bisection to find the root of a function (described by an object that implements the MappingDouble interface), which must lie between x1 and x2.

Explanation
FinitelyGeneratedSet
GeneralizedChoquetIntegral	Use Walley generalization of the Choquet lower and upper integrals to obtain the lower and upper expectations of 2-monotone capacities.
IFBayesNet	Auxiliar class that stores the temporary information about a BayesNet, before it is possible to actually create a BayesNet object
IFProbabilityEntry
IFProbabilityFunction	Auxiliar class that stores the temporary information * about a ProbabilityFunction, before it is possible to * actually create a ProbabilityFunction object (because * not all variables may be read at this point).
IFProbabilityVariable	Auxiliar class that stores the temporary information * about a ProbabilityVariable.
