This note contains a short and simple proof of Wormald's differential equation method (that yields slightly improved approximation guarantees and error probabilities). This powerful method uses differential equations to approximate the time-evolution/dynamics of random processes and algorithms.

  1. Fluid limit and gelation in the frozen Erd\H{o}s-R\'enyi random graph

    math.PR 2025-02 conditional novelty 7.0 of 10

    The frozen Erdős-Rényi graph has a fluid limit governed by explicit ODEs, and its total gelation time rescaled by n converges to a Gumbel distribution with explicit constants.

  2. Online matching on stochastic block model

    cs.DS 2025-06 conditional novelty 6.0 of 10

    For online matching on sparse stochastic block models, greedy and balance policies have fluid limits described by an ODE and a differential inclusion, with an ETC bandit variant achieving sublinear regret.

  3. A random walk among random graphs

    math.PR 2024-12 unverdicted

    These lecture notes provide a pedagogical tour of random walk and random graph theory, covering standard results without claiming new research advances.
