Statistically Efﬁcient Greedy Equivalence Search

Websearch algorithms can be shown to achieve global optimality in the large sample limit even with a relatively sparse search space. One of the best-known procedures of this kind is Greedy Equivalence Search (GES) [Chickering, 2002]. The standard score-based GES algorithm requires a scor-ing criterion to evaluate each candidate graph.
