摘要:

竞争平衡模型已经被提出作为平衡模型的扩展,以解决签名网络中的利益冲突arXiv:2001.04664。在这一模式中,两种不同的范式由于相互竞争的利益而相互竞争,以主导系统并强加自己的价值观。本文利用平均场方法研究了竞争平衡模型的热行为。结果表明,在一定温度下,两个竞争利益之间的对称性将自发地打破,导致离散的相变。因此,从一个异质的签名网络开始,如果代理人的目标是最终减少平衡理论产生的紧张局势,进化最终只选择一个现有的利益和稳定性出现在一个范式主导的网络。临界温度与节点数呈线性关系,这在热平衡理论中也是线性关系。最后通过一系列仿真验证了平均场论的结果。

英文摘要:

Competitive balance model has been proposed as an extension to the balance model to address the conflict of interests in signed networks arXiv:2001.04664 . In this model two different paradigms compete with each other due to the competitive interests to dominate the system and impose their own values. Using mean-field solution method in this paper, we examine the thermal behavior of the competitive balance model. Our results show that under a certain temperature, the symmetry between two competitive interests will spontaneously break which leads to a discrete phase transition. So, starting with a heterogeneous signed network, if agents aim to ultimately decrease tension stemming from balance theory, evolution ultimately chooses only one of the existing interests and stability arises where one paradigm dominates the network. The critical temperature depends linearly on the number of nodes, which was a linear dependence in the thermal balance theory as well. Finally the results obtained through the mean-field theory are verified by a series of simulations.
