Fame Emerges as a Result of Small Memory

摘要

A dynamic memory model is proposed in which an agent ``learns'' a new agentby means of recommendation. The agents can also ``remember'' and ``forget''.The memory size is decreased while the population size is kept constant.``Fame'' emerged as a few agents become very well known in expense of themajority being completely forgotten. The minimum and the maximum of fame changelinearly with the relative memory size. The network properties of thewho-knows-who graph, which represents the state of the system, areinvestigated.
