tau-LevelIndex: Towards Efficient Query Processing in Continuous Preference Space

Summary: tau-LevelIndex: a general index for continuous preference space enabling fast processing of top-k queries (kSPR, UTK, ORU). Efficient construction exploiting space properties; experiments show low space/time costs and 2–3 orders of magnitude speedups over specialized solutions. (summarized by gpt-5-nano on Feb 09 2026)
