Cooperative behavior that increases the fitness of others at a cost to oneself can be
promoted by natural selection only in the presence of an additional mechanism. One such …

Abstract Models of strategy evolution on static networks help us understand how population
structure can promote the spread of traits like cooperation. One key mechanism is the …

This paper proposes a new model, based on the theory of nonlinear dynamical systems, to
study the evolution of cooperation in arbitrary complex networks. We consider a large …

Situations of conflict giving rise to social dilemmas are widespread in society. One way of
studying these important phenomena is by using simplified models of individual behavior …

We study the problem of cooperative behavior emerging in an environment where individual
behaviors and interaction structures coevolve. Players not only learn which strategy to adopt …

Human populations are both highly cooperative and highly organized. Human interactions
are not random but rather are structured in social networks. Importantly, ties in these …

In spite of its relevance to the origin of complex networks, the interplay between form and
function and its role during network formation remains largely unexplored. While recent …

We consider the coupled dynamics of the adaption of network structure and the evolution of
strategies played by individuals occupying the network vertices. We propose a …

We show that self-organized interdependence promotes the evolution of cooperation in
interdependent networks. The evolution of connections between networks occurs according …

Conventional evolutionary game theory predicts that natural selection favours the selfish
and strong even though cooperative interactions thrive at all levels of organization in living …
