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 …

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 …

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 diversity in wealth and social status is present not only among humans, but throughout
the animal world. We account for this observation by generating random variables that …

Besides the structure of interactions within networks, also the interactions between networks
are of the outmost importance. We therefore study the outcome of the public goods game on …

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 …

To be the fittest is central to proliferation in evolutionary games. Individuals thus adopt the
strategies of better performing players in the hope of successful reproduction. In structured …

Up to now, there have been a great number of studies that demonstrate the effect of spatial
topology on the promotion of cooperation dynamics (namely, the so-called “spatial …

Evolutionary games are studied where the teaching activity of players can evolve in time.
Initially all players following either the cooperative or defecting strategy are distributed on a …
