Complete strategy spaces reveal hidden pathways to cooperation
Zhao Song, Ndidi Bianca Ogbo, Xinyu Wang +3
Understanding how cooperation emerges and persists is a central challenge in evolutionary game theory. Existing models often rely on restricted, hand-picked strategy sets, which ca…
Trilobite tridents: A model of lift, drag and stability for queue formation
Hugh A. Trenchard, Carlton E. Brett, Matjaz Perc
The trident like cephalic projections of Walliserops trifurcatus have been interpreted as sexually selected weapons for intraspecific combat. We evaluate one possible, alternative…
Eco-evolutionary cyclic dominance among predators, prey, and parasites
Sayantan Nag Chowdhury, Jeet Banerjee, Matjaž Perc +1
Predator prey interactions are one of ecology's central research themes, but with many interdisciplinary implications across the social and natural sciences. Here we consider an of…
Oppressed species can form a winning pair in a multi-species ecosystem
Attila Szolnoki, Matjaz Perc
The self-protection of alliances against external invaders is a key concept behind the maintenance of biodiversity in the face of natural selection. But since these alliances, whic…
Eco-evolutionary dynamics of cooperation in the presence of policing
Sayantan Nag Chowdhury, Srilena Kundu, Jeet Banerjee +2
Ecology and evolution are inherently linked, and studying a mathematical model that considers both holds promise of insightful discoveries related to the dynamics of cooperation. I…
Exit rights open complex pathways to cooperation
Chen Shen, Marko Jusup, Lei Shi +3
We study the evolutionary dynamics of the prisoner's dilemma game in which cooperators and defectors interact with another actor type called exiters. Rather than being exploited by…
