Variability in Data Streams
Summary: Introduce a stream parameter “variability” v for distributed non‑monotonic update streams and show how to adapt monotone-stream algorithms to track integer functions with small relative error so communication scales as Õ(v) instead of Θ(n). Prove v=O(log f(n)) for monotone streams and v=o(n) for nearly‑monotone or random-walk inputs, implying practical, smoothly degrading communication bounds and minor algorithmic modifications.
