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 …

The pursuit of highest payoffs in evolutionary social dilemmas is risky and sometimes inferior
to conformity. Choosing the most common strategy within the interaction range is safer …

Educational benefits of online collaborative group work have been confirmed in numerous
research studies. Most frequently cited advantages include the development of skills of …

A collective-risk social dilemma implies that personal endowments will be lost if
contributions to the common pool within a group are too small. Failure to reach the collective …

We have studied the evolution of strategies in spatial public goods games where both

In this paper, we introduce an aspiration-dependent persistence into the spatial prisoner's
dilemma game aimed at promoting cooperation in a population. Based on aspiration, a …
