摘要
Two complementary mechanisms are thought to shape 社會 groups: homophily between 智能體s and structural balance in connected triads. Here we consider N fully connected 智能體s, where each 智能體 has G underlying attributes, and the similarity between 智能體s in attribute space (i.e., homophily) is used to determine the link weight between them. To incorporate structural balance we use a triad-updating rule where only one attribute of one 智能體 is changed intentionally in each update, but this also leads to accidental changes in link weights and even link polarities. The link weight dynamics in the limit of large G is described by a Fokker-Planck equation from which the conditions for a 相變 to a fully balanced state with all links positive can be obtained. This “paradise state” of global 合作 is, however, dif
