Enumeration on Trees with Tractable Combined Complexity and Efficient Updates
Summary: Enumerates MSO query answers on trees represented by nondeterministic tree automata with linear preprocessing and linear per-answer delay (constant-delay for MSO with only free FO variables), combined complexity polynomial in the automaton. Supports leaf insert/delete/relabel updates that restart enumeration in logarithmic time, with update time optimal up to doubly-logarithmic factors. (summarized by gpt-5-mini on Feb 09 2026)
