The Priority R-Tree: A Practically Efficient and Worst-Case Optimal R-Tree

Summary: Introduces the Priority R-tree (PR-tree), the first R-tree variant that guarantees worst-case optimal window-query I/Os: O((N/B)^(1-1/d) + T/B). Establishes asymptotic optimality and demonstrates practical gains over existing R-trees, excelling on extreme data via extensive real and synthetic experiments.
