Positive and negative selective assortment Izquierdo Millán, Segismundo Samuel Izquierdo Millán, Luis Rodrigo Hauert, Christoph Producción Científica 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). 2025-06-24T09:11:36Z 2025-06-24T09:11:36Z 2025 info:eu-repo/semantics/article Journal of Theoretical Biology, 2025, vol. 608, p. 112129 0022-5193 https://uvadoc.uva.es/handle/10324/76097 10.1016/j.jtbi.2025.112129 112129 Journal of Theoretical Biology 608 eng https://www.sciencedirect.com/science/article/pii/S0022519325000955 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2025 The Author(s) Atribución 4.0 Internacional Elsevier SI
