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 …

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 …

Game theory is one of the key paradigms behind many scientific disciplines from biology to
behavioral sciences to economics. In its evolutionary form and especially when the …

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 …

Population structure is a key determinant in fostering cooperation among naturally self-
interested individuals in microbial populations, social insect groups, and human societies …

We study the evolution of public cooperation on two interdependent networks that are
connected by means of a utility function, which determines to what extent payoffs in one …

Traditionally, the evolution of cooperation has been studied on single, isolated networks. Yet
a player, especially in human societies, will typically be a member of many different …

Biologists have devoted much attention to assortative mating or homogamy, the tendency for
sexual species to mate with similar others. In contrast, there has been little theoretical work …

Strategy changes are an essential part of evolutionary games. Here, we introduce a simple
rule that, depending on the value of a single parameter w, influences the selection of players …

We show that strategy-independent adaptations of random interaction networks can induce
powerful mechanisms, ranging from the Red Queen to group selection, which promote …
