Recent decades have seen a rise in the use of physics methods to study different societal
phenomena. This development has been due to physicists venturing outside of their …

Why would natural selection favor the prevalence of cooperation within the groups of selfish
individuals? A fruitful framework to address this question is evolutionary game theory, the …

Complex systems are very often organized under the form of networks where nodes and
edges are embedded in space. Transportation and mobility networks, Internet, mobile phone …

Prevalence of cooperation within groups of selfish individuals is puzzling in that it contradicts
with the basic premise of natural selection. Favoring players with higher fitness, the latter is …

Evolutionary game dynamics is one of the most fruitful frameworks for studying evolution in
different disciplines, from Biology to Economics. Within this context, the approach of choice …

Understanding the mechanisms that can lead to the evolution of cooperation through natural
selection is a core problem in biology. Among the various attempts at constructing a theory …

We investigate the cooperation dynamics attributed to the interplay between the evolution of
individual strategies and evolution of individual partnerships. We focus on the effect of …

The evolution of cooperation in network-structured populations has been a major focus of
theoretical work in recent years. When players are embedded in fixed networks, cooperators …

We study evolutionary game dynamics in finite populations. We analyze an evolutionary
process, which we call pairwise comparison, for which we adopt the ubiquitous Fermi …

We introduce a model in which individuals differ in the rate at which they seek new
interactions with others, making rational decisions modeled as general symmetric two-player …
