Recursive Strategies for Answering Recursive Queries - The RQA/FQI Strategy
Summary: Shows QSQR can miss answers for recursive queries. Introduces RQA/FQI, combining recursive expansion with efficient least-fixed-point iteration, and proves completeness over function-free Horn clauses while improving evaluation efficiency. (summarized by gpt-5.6-luna on Jul 24 2026)
