Adding Disjunction to Datalog (Extended Abstract)
Summary: Analyze disjunctive Datalog (disjunctive rule heads) under minimal-model, perfect-model, and stable-model semantics, proving the brave-query variants coincide and exactly capture the complexity class Σ^P_2. Establish combined complexity of disjunctive Datalog as NEXPTIME^NP-complete. (summarized by gpt-5-mini on Feb 09 2026)
