Efficient Top-k Indexing via General Reductions
Summary: General reductions in external memory that transform prioritized-reporting (threshold queries) into static top-k structures with only an O(log_B n) query-time slowdown under mild conditions. Combining prioritized-reporting with max-reporting gives expected-time top-k with no asymptotic slowdown in space, query, or updates; techniques apply to many geometric queries and also work in RAM.
