阿克塞尔罗德模型中的介质效应
The media effect in Axelrod's model explained
摘要：
我们重新审视的问题，引入外部的全球领域-大众媒体-在阿克塞尔罗德的社会动力学模型，除了他们最近的邻居，代理人可以与一个虚拟的邻居，其文化特征是固定的从一开始。自从十多年前首次报道这一现象以来，人们一直认为这一表面上看起来像是一个磁场的现象实际上增加了文化的多样性。在这里，我们提供了一个简单的解释，这是基于行人的观察，阿克塞尔罗德的模型表现出更多的文化多样性，即，更明显的文化领域，当代理人被允许单独与媒体场互动时，而不是当他们可以与邻居互动时。从这个角度来看，这是当地的相互作用，努力使吸收配置不那么支离破碎相比，在极端的情况下，代理人与媒体的互动。
英文摘要：
We revisit the problem of introducing an external global field -- the mass media -- in Axelrod's model of social dynamics, where in addition to their nearest neighbors, the agents can interact with a virtual neighbor whose cultural features are fixed from the outset. The finding that this apparently homogenizing field actually increases the cultural diversity has been considered a puzzle since the phenomenon was first reported more than a decade ago. Here we offer a simple explanation for it, which is based on the pedestrian observation that Axelrod's model exhibits more cultural diversity, i.e., more distinct cultural domains, when the agents are allowed to interact solely with the media field than when they can interact with their neighbors as well. In this perspective, it is the local homogenizing interactions that work towards making the absorbing configurations less fragmented as compared with the extreme situation in which the agents interact with the media only.
