Class RandomIncisionFunction<T extends Formula>

java.lang.Object

net.sf.tweety.beliefdynamics.kernels.RandomIncisionFunction<T>

Type Parameters:

T - The formula this incision function works on

All Implemented Interfaces:

IncisionFunction<T>

public class RandomIncisionFunction<T extends Formula>
extends java.lang.Object
implements IncisionFunction<T>

This class implements an incision function that just randomly selects a minimal incision.
NOTE: results of this function are not deterministic and may not be reproduced (however each result is a valid incision)

Method Detail

incise

public java.util.Collection<T> incise(java.util.Collection<java.util.Collection<T>> kernelSets)

Description copied from interface: IncisionFunction

Selects from each collection in the given collection one element and returns the collection of all those elements.

Specified by:

incise in interface IncisionFunction<T extends Formula>

Parameters:

kernelSets - a collection of kernel sets.

Returns:

the selected elements.

isIncision

private boolean isIncision(java.util.Collection<java.util.Collection<T>> kernelSets,
                           java.util.Collection<T> possibleIncision)

Checks whether possibleIncision is an incision, ie. whether each kernel is incised.

Parameters:

kernelSets - a set of kernels.

possibleIncision - a possible incision.

Returns:

"true" if the given set is an incision.
