Simple & Optimal Quantile Sketch: Combining Greenwald-Khanna with Khanna-Greenwald
Summary: Deterministic simplification of the Greenwald–Khanna sketch stores at most (2+o(1)) ε^{-1} log(εn) elements, matching optimal space for additive ε-approximate quantiles. Simplified analysis enables practical data-structure implementation with per-element time O(log(1/ε)+log log(εn)); extends to weighted quantiles with improved bounds.
