Best Position Algorithms for Top-k Queries

Summary: Proposes BPA and BPA2 for top-k on sorted lists, beating the Threshold Algorithm (TA). BPA stops earlier; its stop position and cost can be (m-1)× lower than TA, while BPA2 reduces list accesses by roughly (m-1)×, with experiments showing gains. (summarized by gpt-5-nano on Feb 09 2026)
