我们研究人口结构中的合作的演变，在大量的可变大小的群体，随机迁移率m连接。社会互动，包括合作和竞争，只发生在群体内部。假设群体很大，我们定义一个参数λ来衡量当地监管的力度，即，群体规模的刚性。个体有两种可能的基因型，一种通常被认为产生非合作表型，另一种是与自己群体的所有成员合作的表型。基因的作用可能是加性的，产生的适应度函数在一个群体中的合作者的数量上是线性的，或者不是。假设弱选择，我们得到以下两个相反的结论。(1)“汉密尔顿政权”：如果λ << m，那么合作行为在一定条件下可以传播，这在加法中，即，线性的情况下，正是汉密尔顿的规则。该条件的一般版本也相对容易应用，并且基于Wright的无限岛模型中等位基因频率的经典β分布。我们称之为“测试版的汉密尔顿法则”。(2)“泰勒制度”：如果m << λ，那么对行动者来说代价高昂的合作就会被选择所淘汰。
We study evolution of cooperation in a population structured in a large number of groups of variable size, connected by random migration at rate m. Social interactions, including cooperation and competition occur only inside the groups. Assuming that groups are large, we define a parameter λ that measures the strength of the local regulation, i.e., the rigidity of group sizes. Individuals are of two possible genotypes, one typically assumed to produce a non-cooperative phenotype and the other a phenotype that is cooperative with all members of its own group. Gene action may be additive, producing fitness functions that are linear in the number of cooperators in a group, or not. Assuming weak selection, we obtain the following two contrasting conclusions. (1) “Hamilton regime”: If λ << m, then cooperative behavior can spread under a certain condition, which in the additive, i.e., linear, case is precisely Hamilton’s rule. The general version of this condition is also relatively easy to apply and is based on Wright’s classical beta distribution for the frequency of alleles in infinite island models. We call it the “beta version of Hamilton’s rule”. (2) “Taylor regime”: If m << λ, then cooperation that is costly to the actor is eliminated by selection.
