WebOct 26, 2024 · The Greedy Equivalence Search (GES) algorithm uses this trick. GES starts with an empty graph and iteratively adds directed edges such that the improvement in a model fitness measure (i.e. score) is maximized. An example score is the Bayesian Information Criterion (BIC) . Webthe search by moving between equivalence classes rather than between individual graphs.
