On the Cyclic to Acyclic Scheme Transformation and Solving Cyclic Queries (Extended Abstract)
Summary: Shows equivalence (on simple schemes) between minimizing joins to make a cyclic schema acyclic and minimizing joins to solve cyclic natural-join queries, proves both NP-complete. Gives a polynomial-time algorithm when the scheme's dual graph is chordal and ties to edge-contraction complexity. (summarized by gpt-5-mini on Feb 09 2026)
