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. Classical Webcalled the Greedy Equivalence Search (GES). The algorithm was further developed and studied by Chickering [Chickering, 2002]. GES is a Bayesian algorithm that heuristically searches the space of CBNs and returns the model with highest Bayesian score it finds. In particular, GES starts its search with the empty graph.
