基于博弈论的意见形成模型

Opinion formation models based on game theory

Alessandro Di Mare, Vito Latora

摘要:

提出了一种在战略博弈论的背景下模拟两个不同意见的个体之间的基本互动的方法。各种游戏被认为是,产生不同种类的意见形成动态。首先,通过假设所有个体(参与者)都是平等的,得到了Deffuant等人提出的连续观点动力学的有界置信模型,在该模型中定义了一个容忍阈值,使得观点差异大于该阈值的个体不能进行交互.然后,我们认为,个人有不同的倾向,以改变意见和不同的能力,说服他人。通过这种方式,我们得到了所谓的“固执的个人和演说家”(SO)模型,这是Deffuant等人模型的推广,其中每对个体的阈值容忍度是不同的。我们探索,通过数值模拟,SO模型的动力学,我们提出了进一步的概括,可以实现。

英文摘要:

A way to simulate the basic interactions between two individuals with different opinions, in the context of strategic game theory, is proposed. Various games are considered, which produce different kinds of opinion formation dynamics. First, by assuming that all individuals (players) are equals, we obtain the bounded confidence model of continuous opinion dynamics proposed by Deffuant et al. In such a model a tolerance threshold is defined, such that individuals with difference in opinion larger than the threshold can not interact. Then, we consider that the individuals have different inclinations to change opinion and different abilities in convincing the others. In this way, we obtain the so-called ``Stubborn individuals and Orators'' (SO) model, a generalization of the Deffuant et al. model, in which the threshold tolerance is different for every couple of individuals. We explore, by numerical simulations, the dynamics of the SO model, and we propose further generalizations that can be implemented.
