在人类社会和生态系统中，从富人到穷人的利他行为经常被观察到（例如海豚之间的援助，以及吸血蝙蝠和人类之间的食物共享）。在本文中，我们研究了在成对个体不重复互动的情况下，利他行为（我们称之为“同情心”）如何演变。计算机模拟的结果显示出以下两个结果：（1）存在三种类型的进化动力学：（i）从不帮助别人的无条件非帮助者占主导地位； (ii) 帮助处境比自己更糟糕的人的富有同情心的人和总是帮助别人的无条件帮助者并存； (iii) 无条件帮助者和无条件不帮助者的周期性主导地位。 (2)在一定的参数设置下，稳定地实现了约60~70%的行为是利他的合作社会。
Altruistic behaviors from the haves to the have-nots are often observed in human societies and ecosystems (e.g. assistance among dolphins, and food sharing among vampire bats and among human beings). In this paper, we investigate how the altruistic behaviors, which we call “compassion”, evolve in the situation where pairs of individuals do not repeatedly interact. The results of the computer simulation show the following two results: (1) There exist three types of evolutionary dynamics: (i) the dominance of unconditional non-helpers who never help others; (ii) the coexistence of compassionate individuals who help others who are worse off than themselves and unconditional helpers who always help others; and (iii) the cyclical dominance of unconditional helpers and unconditional non-helpers. (2) Under some parameter settings, cooperative societies where about 60~70% of actions are altruistic are stably realized.
