The study of graphical causal models is fundamentally the study of separations and conditional independences. We provide linear-time algorithms for two graphical primitives: to test, if a given set is a minimal d -separator, and to find a minimal d -separator in directed acyclic graphs (DAGs), completed partially directed acyclic graphs (CPDAGs) and restricted chain graphs (RCGs) as well as minimal m - separators in ancestral graphs (AGs). These algorithms improve the runtime of the best previously known algorithms for minimal separators that are based on moralization and thus require quadratic time to construct and handle the moral graph. (Minimal) separating sets have important applications like finding (minimal) covariate adjustment sets or conditional instrumental variables.
