The Axelrod-Schelling model incorporates into the original Axelrod's model of cultural dissemination the possibility that cultural agents placed in culturally dissimilar environments move to other places, the strength of this mobility being controlled by an intolerance parameter. By allowing heterogeneity in the intolerance of cultural agents, and considering it as a cultural feature, i.e., susceptible of cultural transmission (thus breaking the original symmetry of Axelrod-Schelling dynamics), we address here the question of whether tolerant or intolerant traits are more likely to become dominant in the long-term cultural dynamics. Our results show that tolerant traits possess a clear selective advantage in the framework of the Axelrod-Schelling model. We show that the reason for this selective advantage is the development, as time evolves, of a positive correlation between the number of neighbors that an agent has in its environment and its tolerant character.
阿克塞尔罗德 - 谢林模型在阿克塞尔罗德最初的文化传播模型中纳入了这样一种可能性：处于文化差异环境中的文化主体会迁移到其他地方，这种迁移的强度由一个不容忍参数控制。通过允许文化主体的不容忍存在异质性，并将其视为一种文化特征，即能够进行文化传播（从而打破了阿克塞尔罗德 - 谢林动力学的原始对称性），我们在此探讨宽容或不宽容特征在长期文化动态中更有可能占据主导地位的问题。我们的结果表明，在阿克塞尔罗德 - 谢林模型的框架内，宽容特征具有明显的选择优势。我们表明，这种选择优势的原因是随着时间的推移，主体在其环境中的邻居数量与其宽容特征之间形成了正相关。
