All Implemented Interfaces:

BeliefBaseMachineShop

public class PenalizingCreepingMachineShop
extends AbstractCreepingMachineShop

This class is capable of restoring consistency of a possible inconsistent probabilistic conditional belief set. Restoring consistency is performed by biased creeping of the original belief set using the cuplability vector, see [Diss, Thimm] for details.

Repairs the given belief base, i.e. restores consistency.

Specified by:

repair in interface BeliefBaseMachineShop

Overrides:

repair in class AbstractCreepingMachineShop

Parameters:

beliefBase - a possibly inconsistent belief base.

Returns:

a consistent belief base that is as close as possible to the given belief base. NOTE: if the given belief base is consistent this method is expected to return it unmodified.
