Abstract

We present algorithms for testing language inclusion L(A) ⊆ L(B) between tree automata in time O(|A| · |B|) where B is deterministic (bottom-up or top-down). We extend our algorithms for testing inclusion of automata for unranked trees A in deterministic DTDs or deterministic EDTDs with re- strained competition D in time O(|A| · |Σ| · |D|). Previous algorithms were less efficient or less general.
