In this note we present an algebraic verification of Segall's Propagation of Information with Feedback (PIF) algorithm. This algorithm serves as a nice benchmark for verification exercises (see [2, 13, 8]). The verification is based on the methodology presented in [7] and demonstrates its applicability to distributed algorithms.
