The algorithm is appeal-ing … Webrely on local heuristics to enforce the acyclicity. For example, Greedy Equivalence Search (GES) enforces acyclicity one edge at a time, explicitly checking for the acyclicity constraint when an edge is added. GES is known to ﬁnd the global minimizer with inﬁnite samples under suitable assumptions (Chickering, 2002; Nandy et al., 2024), but ...

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 Webequivalence class of ancestral graph Markov models (Richardson and Spirtes, 2002; Zhang, 2008a,b). More recently, Ogarrio et al.
