论文摘要
直接互惠是解决我们社会生活中合作的关键机制之一。根据最近的理解，大多数直接互惠的古典策略都属于两个类别之一，即“伙伴”或“竞争对手”。 “合作伙伴”是实现相互合作的慷慨策略，“竞争对手”永远不会让同事变得更好。他们的工作条件不同：例如，合作伙伴在大量人口中表现出色，而竞争对手在正面比赛中表现出色。通过详尽的枚举，我们证明了作为伴侣和竞争对手的策略的存在。其中，我们专注于人类解剖策略，其五种特征成分，即合作，接受，惩罚，康复和缺陷，否则为“ Capri”。我们的进化模拟在广泛的环境条件下显示出CAPRI的出色性能。
Direct reciprocity is one of the key mechanisms accounting for cooperation in our social life. According to recent understanding, most of classical strategies for direct reciprocity fall into one of two classes, `partners' or `rivals'. A `partner' is a generous strategy achieving mutual cooperation, and a `rival' never lets the co-player become better off. They have different working conditions: For example, partners show good performance in a large population, whereas rivals do in head-to-head matches. By means of exhaustive enumeration, we demonstrate the existence of strategies that act as both partners and rivals. Among them, we focus on a human-interpretable strategy, named `CAPRI' after its five characteristic ingredients, i.e., cooperate, accept, punish, recover, and defect otherwise. Our evolutionary simulation shows excellent performance of CAPRI in a broad range of environmental conditions.
