Positive and negative selective assortment Izquierdo, Segismundo S. Izquierdo Millán, Luis Rodrigo Hauert, Christoph Negative assortment Selective assortment Evolutionary dynamics Sociología Informática Gestión de empresas Sociology Computer science Industrial management 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).
