Title:Bounded-confidence opinion models with random-time interactions

Abstract:In models of opinion dynamics, the opinions of individual agents evolve with time. One type of opinion model is a bounded-confidence model (BCM), in which opinions take continuous values and interacting agents compromise their opinions with each other if those opinions are sufficiently similar. In studies of BCMs, it is typically assumed that interactions between agents occur at deterministic times. This assumption neglects an inherent element of randomness in social systems. In this paper, we study BCMs on networks and allow agents to interact at random times. To incorporate random-time interactions, we use renewal processes to determine social interactions, which can follow arbitrary waiting-time distributions (WTDs). We establish connections between these random-time-interaction BCMs and deterministic-time-interaction BCMs. We find that BCMs with Markovian WTDs have consistent statistical properties on different networks but that the statistical properties of BCMs with non-Markovian WTDs depend on network structure.
