摘要
We consider 社會 systems in which 智能體s are not only characterized by their states but also have the freedom to choose their interaction partners to maximize their utility. We map such systems onto an Ising模型 in which spins are dynamically coupled by links in a dynamical 網絡. In this model there are two dynamical quantitieswhich arrange towards a minimum energy state in the canonical framework:the spins, s(i), and the adjacency matrix elements, c(ij).The model is exactly solvable because microcanonical partition functions reduce to productsof binomial factors as a direct consequence of the c(ij) minimizing energy. We solve the system for finite sizes and for the two possible 熱力學 limits and discussthe phase diagrams.
