摘要：This paper investigates opinion intervention of the heterogeneous Deffuant-Weisbuch (DW) model in social networks, whose bounded confidence and the random encounter communication mechanism make the evolutionary outcomes almost unpredictable. We employ a goal-oriented leader and a coordinating leader to guide the divisive and unpredictable public opinions to a desired state. The goal-oriented leader maintains the desired state, while the coordinating leader, with a large confidence threshold, guides agents towards the goal-oriented leader. Both leaders follow the same DW model update rules as normal agents and do not alter normal agents' opinion update rules or require their private information, thus ensuring a gentle intervention process. We theoretically derive a necessary and sufficient condition on the parameters of the leaders for them to guide all agents' opinions to reach consensus at the desired state almost surely, regardless of the parameters of normal agents. Furthermore, we prove that both types of leaders are necessary for successful intervention, whereas one leader alone is insufficient. (c) 2025 Published by Elsevier Ltd.
