Finding Nonrecursive Envelopes for Datalog Predicates
Summary: Proves that finding tight nonrecursive conjunctive envelopes for Datalog fixpoints is undecidable; tight lower envelopes iff boundedness, but tight upper envelopes can exist for unbounded predicates. Presents a decidable relaxation—connected envelopes—with an algorithm and applications. (summarized by gpt-5-mini on Feb 09 2026)
