Expanding Reverse Nearest Neighbors
Summary: ERNN: choose up to k edge weight reductions to maximize a facility's reverse nearest neighbor set; problem is NP-hard, APX-hard, non‑monotone and non‑submodular. Propose greedy heuristics that prune edges and cut per‑edge cost, giving orders‑of‑magnitude speedups and large RNN gains. (summarized by gpt-5-mini on Feb 09 2026)
