Once the simulation is started, we observe agents commuting to work, going to restaurants to eat and going to pubs to meet friends. When the simulation begins, there are no agent social networks. However, as the simulation runs, the agents make friendships. We observe social ties quickly emerging between agents. Shortly after the simulation has begun, the agents have self-organized into coherent social networks. According to our model of social interaction, social ties between agents appear and strengthen as they meet in the physical world. Every day at midnight, all social network edges are decreased by a factor, leading to weak links to disappear, leading to friendless agents becoming ejected from the large social network.
