Abstract
The representation problem of independence models is studied by focusing on acyclic directed graph (DAG). We present the algorithm PC* in order to look for a perfect map. However, when a perfect map does not exist, so that PC* fails, it is interesting to find a minimal I-map, which represents as many triples as possible in J *. Therefore we describe an algorithm which finds such a map by means of a backtracking procedure. © 2011 Springer-Verlag Berlin Heidelberg.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
