Semantic Acyclicity on Graph Databases

Summary: Characterize semantic acyclicity for UC2RPQs over graph databases: decidable in 2EXPSPACE and EXPSPACE-hard (even without inverses). Evaluation of semantically acyclic UC2RPQs is FPT; provide a robust approximation theory when no equivalent acyclic UC2RPQ exists. (summarized by gpt-5-mini on Feb 09 2026)
