The V*-Diagram: A Query-Dependent Approach to Moving KNN Queries

Summary: V*-Diagram is a query-dependent safe-region method for MkNN queries that uses the query position and search-space context, not data objects alone. It reduces IO and computation dramatically, with experiments showing ~100× speedups. (summarized by gpt-5-nano on Feb 09 2026)
