In populations subject to evolutionary processes, the assortment of players with different genes or strategies can have a large impact on players' payoffs and on the expected evolution of each strategy in the population. Here we consider assortment generated by a process of partner choice known as selective assortment. Under selective assortment, players looking for a mate can observe the strategies of a sample of potential mates or co-players, and select one of them to interact with. This selection mechanism can generate positive assortment (preference for players using the same strategy), or negative assortment (preference for players using a different strategy). We study the impact of selective assortment in the evolution and in the equilibria of a population, providing results for different games under different evolutionary dynamics (including the replicator dynamics).

Keywords: Assortment; evolutionary dynamics; negative assortment; selective assortment.

在受到进化过程影响的群体中，拥有不同基因或策略的玩家之间的配对方式会对玩家们的收益以及每种策略在群体中的预期演化产生重大影响。在这里，我们考虑由一种称为选择性配对的过程生成的配对情况。在这种选择性配对过程中，寻找伴侣的玩家可以观察到潜在伴侣或合作对象中不同策略的一组样本，并从中挑选一位进行互动。这种选择机制可以产生正向配对（偏好使用相同策略的玩家）或负向配对（偏好使用不同策略的玩家）。我们研究了选择性配对在群体演化和均衡中的影响，提供了不同类型博弈在不同进化动力学（包括复制者动态）下的结果。
