Package edu.cmu.tetrad.search

Class Cfci

java.lang.Object
edu.cmu.tetrad.search.Cfci
All Implemented Interfaces:
GraphSearch
public final class Cfci extends Object implements GraphSearch
Extends Erin Korber's implementation of the Fast Causal Inference algorithm (found in FCI.java) with Jiji Zhang's Augmented FCI rules (found in sec. 4.1 of Zhang's 2006 PhD dissertation, "Causal Inference and Reasoning in Causally Insufficient Systems").

This class is based off a copy of FCI.java taken from the repository on 2008/12/16, revision 7306. The extension is done by extending doFinalOrientation() with methods for Zhang's rules R5-R10 which implements the augmented search. (By a remark of Zhang's, the rule applications can be staged in this way.)
