An Almost Tight Lower Bound for Plurality Consensus with Undecided State Dynamics in the Population Protocol Model

Year: 2025

Type: conference-paper

Abstract: We revisit the majority problem in the population protocol communication model, as first studied by Angluin et al. (Distributed Computing 2008). We consider a more general version of this problem known as plurality consensus, which has already been studied intensively in the literature. In this problem, each node in a system of n nodes, has initially one of k different opinions, and they need to agree on the (relative) majority opinion. In particular, we consider the important and intensively studied model of Undecided State Dynamics.
