public static boolean existsInducingPathInto(Node x,
 Node y,
 Graph graph)

existsInducingPathInto.

Parameters:

x - a Node object

y - a Node object

graph - a Graph object

convert

public Graph convert()

This method does the convertion of DAG to PAG.

Returns:

Returns the converted PAG.

getKnowledge

public Knowledge getKnowledge()

Getter for the field knowledge.

Returns:

a Knowledge object

setKnowledge

public void setKnowledge(Knowledge knowledge)

Setter for the field knowledge.

Parameters:

knowledge - a Knowledge object

isCompleteRuleSetUsed

public boolean isCompleteRuleSetUsed()

isCompleteRuleSetUsed.

Returns:

true if Zhang's complete rule set should be used, false if only R1-R4 (the rule set of the original FCI) should be used. False by default.
