Evolution of Leadership : Simulation/Experiment Approach.

点击翻译按钮获取中文摘要

Hierarchical social structures based on agents' leadership are often observed in human societies or in groups of social animals who usually live in groups. We investigate the effect of game structures on the evolution of the social structure, especially the hierarchical structure, in a group of interacting individuals, using evolutionary game approach and genetic algorithms. The simulation results show that the evolutionary process for a class of 2x2 games similar to the game of leader brings about linear dominance hierarchies among strategy (automaton) classes based on agents' leader-follower relationships.
