Efficient Regular Simple Path Queries under Transitive Restricted Expressions
Summary: Define transitive restricted expressions (covering >99% of real-world RSPQs) and give an exact framework for reachability and enumeration for them. New reachability tests, candidate pruning, and redundancy elimination achieve near-approximate speeds and up to 100× exact-method speedups. (summarized by gpt-5-mini on Feb 09 2026)
