"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.
