Class JunctionTreeAlgorithm

java.lang.Object
  unbbayes.prs.bn.JunctionTreeAlgorithm

All Implemented Interfaces:

IInferenceAlgorithm

public class JunctionTreeAlgorithm
extends Object
implements IInferenceAlgorithm

Class for junction tree compiling algorithm. It includes basic consistency check for single entity networks. By now, this is still a wrapper for ProbabilisticNetwork.compile(). TODO gradually migrate every compilation routine from ProbabilisticNetwork to here.
