WebWe introduce Selective Greedy Equivalence Search (SGES), a restricted version of Greedy Equivalence Search (GES). SGES retains the asymptotic correctness of GES but, unlike GES, has polynomial performance guarantees. In particular, we show that when data are sampled independently from a distribution that is perfect with respect to a DAG G … 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. greek heritage in ethics
