The (Almost) Complete Guide to Tree Pattern Containment
Summary: Comprehensive reclassification of tree-pattern query containment/validity/satisfiability with and without schema, unifying prior results and resolving long-open complexity gaps via novel automata/reduction techniques. Pinpoints exact tractability and hardness boundaries for patterns on trees (and graphs). (summarized by gpt-5-mini on Feb 09 2026)
