VcPc
Constructs a CPC algorithm that uses the given independence test as oracle. This does not make a copy of the independence test, for fear of duplicating the data set!

isMeekPreventCycles
public boolean isMeekPreventCycles()- Returns:
- true just in case edges will not be added if they would create cycles.
-
setMeekPreventCycles
public void setMeekPreventCycles(boolean meekPreventCycles) Sets to true just in case edges will not be added if they would create cycles. -
getElapsedTime
public long getElapsedTime()- Returns:
- the elapsed time of search in milliseconds, after
search()
has been run.
-
getKnowledge
- Returns:
- the knowledge specification used in the search. Non-null.
-
setKnowledge
Sets the knowledge specification used in the search. Non-null. -
getIndependenceTest
- Returns:
- the independence test used in the search, set in the constructor. This is not returning a copy, for fear of duplicating the data set!
-
getDepth
public int getDepth()- Returns:
- the depth of the search--that is, the maximum number of variables conditioned on in any conditional independence test.
-
setDepth
public void setDepth(int depth) Sets the maximum number of variables conditioned on in any conditional independence test. If set to -1, the value of 1000 will be used. May not be set to Integer.MAX_VALUE, due to a Java bug on multi-core systems. -
getAmbiguousTriples
- Returns:
- the set of ambiguous triples found during the most recent run of the algorithm. Non-null after a call to
search()
.
-
getColliderTriples
- Returns:
- the set of collider triples found during the most recent run of the algorithm. Non-null after a call to
search()
.
-
getNoncolliderTriples
- Returns:
- the set of noncollider triples found during the most recent run of the algorithm. Non-null after a call
to
search()
.
