Errata for "SpaceSaving±: An Optimal Algorithm for Frequency Estimation and Frequent Items in the Bounded-Deletion Model"
Summary: Erratum exposes SpaceSaving±’s hidden assumption that deletions follow all insertions: interleaving can cause severe underestimation. Provides a minimally modified bounded-deletion algorithm supporting interleaved updates, with pointers to its full analysis. (summarized by gpt-5.6-luna on Jul 24 2026)
