我们研究意见动态多路复用网络中的代理人有界的信心。也就是说,两个相邻的个体交换意见,如果他们的意见不超过给定的阈值,则进行妥协。在文献中,代理人通常被假定有一个均匀的置信区间。在这里,我们研究分析和数值上的意见演变结构化网络的特点是多层次的各自的置信阈值和一般的初始意见分布。通过严格的概率分析,我们分析表明,在一个相变发生在长期的共识行为的临界阈值,在多路复用网络与一些规律性的条件。我们的结果揭示了临界阈值与初始分布之间的定量关系。此外,我们的数值模拟说明了网络拓扑结构,包括格子和,小世界和无标度网络,以及结构相关的收敛参数容纳节点的异质性的代理的共识行为。我们发现一致性的临界阈值与本文定理4和定理5中的预测上界趋于一致。最后,我们的研究结果表明,当初始意见配置是在一个有界的范围内,多重阻碍共识的形成,并提供洞察信息扩散和社会动态的网络建模的多重系统。
We study opinion dynamics over multiplex networks where agents interact with bounded confidence. Namely, two neighbouring individuals exchange opinions and compromise if their opinions do not differ by more than a given threshold. In literature, agents are generally assumed to have a homogeneous confidence bound. Here, we study analytically and numerically opinion evolution over structured networks characterised by multiple layers with respective confidence thresholds and general initial opinion distributions. Through rigorous probability analysis, we show analytically the critical thresholds at which a phase transition takes place in the long-term consensus behaviour, over multiplex networks with some regularity conditions. Our results reveal the quantitative relation between the critical threshold and initial distribution. Further, our numerical simulations illustrate the consensus behaviour of the agents in network topologies including lattices and, small-world and scale-free networks, as well as for structure-dependent convergence parameters accommodating node heterogeneity. We find that the critical thresholds for consensus tend to agree with the predicted upper bounds in Theorems 4 and 5 in this paper. Finally, our results indicate that multiplexity hinders consensus formation when the initial opinion configuration is within a bounded range and, provide insight into information diffusion and social dynamics in multiplex systems modeled by networks.
