WebJun 6, 2015 · Download PDF Abstract: We 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 … Webdata. Score-based algorithms, such as greedy equivalence search (GES) (Chickering,2002), maximize a particular score function over the space of graphs. Hybrid algorithms such as greedy sparsest permutation (GSP) combine ele-ments of both methods (Solus et al.,2024). Algorithms have also been developed to learn causal graphs
