java.lang.Object

net.sf.tweety.logics.pcl.analysis.AbstractCreepingMachineShop

net.sf.tweety.logics.pcl.analysis.UnbiasedCreepingMachineShop

All Implemented Interfaces:

BeliefBaseMachineShop

public class UnbiasedCreepingMachineShop
extends AbstractCreepingMachineShop

This class is capable of restoring consistency of a possible inconsistent probabilistic conditional belief set. Restoring consistency is performed by an unbiased creeping of the original belief set towards an uniform belief set, see [Diss, Thimm] for details.
