Lazy Updates: An Efficient Technique to Continuously Monitoring Reverse kNN

Summary: Lazy updates for continuous reverse kNN monitoring using rectangular safe regions per query/object to avoid recomputation while inside. Reduces client-server traffic as updates occur only on exit or by server request; cost analysis and experiments show order-of-magnitude gains. (summarized by gpt-5-nano on Feb 09 2026)
