Opinion dynamics is a crucial topic in complex social systems. However, existing models rarely study limited information accessibility, sparse interactions, and the coevolution of opinion and an open-ended structure. In this paper, we propose the Sparse COevolutionary Open-Ended (SCOOE) model. We address the sparse interaction limitation through extrinsic collective interaction and intrinsic observation based on incomplete neighborhood information. We also consider the coevolution of opinion and open-ended structure by studying structure-opinion co-dynamics when dissidents are leaving and when newcomers with novel opinions are joining. From an opinion dynamics perspective, we find that the proposed mechanisms effectively form lean and fast decision strategies to reduce conflicts under uncertainty. The model is robust in boosting and enhancing a global consensus with only small odds of extreme results. The structure evolves toward a small-world network. We find that an emergent dialectic relationship exists between community segregation and community cohesion viewed from a structural dynamics perspective. We also study the influence of agent heterogeneity under different cognitive ability distributions.

开放式社会中稀疏交互的共同进化意见动态

意见动态是复杂社会系统中的一个重要课题。然而,现有模型很少研究有限的信息可访问性、稀疏的交互以及意见的共同演化和开放式结构。在本文中,我们提出了S parse CO进化O pen- nded ( SCOOE) 模型。我们通过基于不完整邻域信息的外部集体交互和内部观察来解决稀疏交互限制。我们还通过研究持不同政见者离开和有新意见的新人加入时的结构-意见协同动力学来考虑意见和开放式结构的共同演化。从意见动态的角度来看,我们发现所提出的机制有效地形成了精益和快速的决策策略,以减少不确定性下的冲突。该模型在促进和增强全球共识方面是稳健的,只有很小的极端结果的可能性。该结构向小世界网络发展。我们发现,从结构动力学的角度来看,社区隔离与社区凝聚力之间存在一种新兴的辩证关系。
