"WebSep 15, 2024 · Description. GES is a score based causal discovery algorithm that outputs a pattern, a graph that encodes the markov equilevence class of a set of DAGs. GES contains score functions for continuous and discrete datasets. Mixed datasets will have to be treated treated as continuous or discretized completly.

WebNP-complete (Chickering, 1995), the optimization is usually performed greedily such as in the prominent Greedy Equivalence Search (GES ) (Chickering, 2002). Finally, hybrid methods have also been considered; Max-Min Hill-Climbing (MMHC ) (Tsamardinos et al., 2006), for example, alternates between constraint- and score-based updates. 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
