论文摘要
我们考虑了与同步分娩和死亡合作的出现的空间模型。 特工带有标签，并通过策略根据自己和对手的标签进行策略来与邻居互动，并与邻居互动。代理商的回报决定了其复制和通过其战略的机会。我们表明，当随机分配标签而不是继承时，大约40〜％的整体的显着异质人群可能会出现并持续存在。具有与他们的标签相同标签并与他人合作的代理商的异性缺陷。在我们的环境中，杂质的出现是通过代理人的回报与其邻居的回报之间的相关性来解释的。当随机分配标签时，异性善（与带有一个人的标签并与他人缺陷的代理合作的优点）使后来的出现比以前想象的更有趣的现象。
We consider a spatial model of the emergence of cooperation with synchronous births and deaths. Agents bear a tag and interact with their neighbors by playing the prisoner's dilemma game with strategies depending on their own and opponent's tags. An agent's payoff determines its chances of reproducing and passing on its strategy. We show that when tags are assigned at random rather than inherited, a significant heterophilic population of about 40~\% of the whole can emerge and persist. Heterophilics defect on agents bearing the same tag as theirs and cooperate with others. In our setting, the emergence of heterophily is explained by the correlation between an agent's payoff and its neighbors' payoffs. The advantage of heterophily over homophily (cooperating with agents bearing one's tag and defecting with others) when tags are assigned at random makes the emergence of the later an even more interesting phenomenon than previously thought.
