The complexity of many biological, social and technological systems stems from the richness
of the interactions among their units. Over the past decades, a variety of complex systems …

Interactions among living organisms, from bacteria colonies to human societies, are
inherently more complex than interactions among particles and non-living matter. Group …

Abstract Recently, Press and Dyson have proposed a new class of probabilistic and
conditional strategies for the two-player iterated Prisoner's Dilemma, so-called zero …

The evolutionary dynamics of the Public Goods game addresses the emergence of
cooperation within groups of individuals. However, the Public Goods game on large …

Reputation has been shown to provide an informal solution to the problem of cooperation in
human societies. After reviewing models that connect reputations and cooperation, we …

While the significance of networks in various human behavior and activities has a history as
long as human's existence, network awareness is a recent scientific phenomenon. The …

Node centrality plays an important role in many dynamical processes taking place on
complex networks. In this work, we associate the individuals' collective influence (CI) with …

In this work, we study the spatial evolutionary public goods game by introducing payoff
aspirations for players, and players update their strategies with a stochastic probability …

In human societies and animal groups, individual behavior is often driven by self-interest,
with actions typically avoided if they do not yield benefits. This paper focuses on payoff …

An open problem in evolutionary game dynamics is to understand the effect of peer pressure
on cooperation in a quantitative manner. Peer pressure can be modeled by punishment …
