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). 0022-5193 http://hdl.handle.net/10259/10460 10.1016/j.jtbi.2025.112129 Negative assortment Selective assortment Evolutionary dynamics Positive and negative selective assortment
