Abstract

In this work, we improve the Hegselmann-Krause model (HK model) by combining the agent's stubbornness and the quantitative impact of stubborn agents on the evolution of other agents’ opinions. We divide stubborn agents into expert stubborn agents, environmentally stubborn agents and intrinsically stubborn agents based on the impact weight and agent's characteristics. We simulate the evolution of opinions of the improved HK model, and find that it is closer to reality. We also study the impact of the influence coefficient and the proportion of intrinsically stubborn agents on the stabilization time, and find that the presence of non-expert stubborn agents reduces the rate of convergence of opinions. Finally, we verify the effectiveness of the improved HK model by two real social events.

基于智能体顽固性和顽固性的Hegselmann-Krause改进模型的意见动态

在这项工作中，我们通过结合代理的顽固性和顽固代理对其他代理意见演变的定量影响，改进了Hegselmann-Krause模型(HK模型)。根据固化剂的影响权重和固化剂的特性，将固化剂分为专家固化剂、环境固化剂和内在固化剂。我们模拟了改进后的HK模型的意见演变，发现它更接近现实。我们还研究了影响系数和本质顽固代理的比例对稳定时间的影响，发现非专家顽固代理的存在降低了意见的收敛速度。最后，通过两个真实的社会事件验证了改进的HK模型的有效性。

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
