WebGreedy Equivalence Search (GES) is a score-based search algorithm that searches over the space of equiv-alence classes of Bayesian-network structures. The al-gorithm is … WebGES is a Bayesian algorithm that heuristically searches the space of CBNs and returns the model with highest score it finds. In particular, GES starts its search with the empty graph. It then performs a forward stepping search in which edges are added between nodes in order to increase the Bayesian score. reach records merchline
