Network science has evolved into an indispensable platform for studying complex systems.
But recent research has identified limits of classical networks, where links connect pairs of …

Evolutionary game theory is a successful mathematical framework geared towards
understanding the selective pressures that affect the evolution of the strategies of agents …

Social dilemmas occur when incentives for individuals are misaligned with group
interests,,,,,–. According to the 'tragedy of the commons', these misalignments can lead to …

A tragedy of the commons occurs when individuals take actions to maximize their payoffs

Reciprocity is a major factor in human social life and accounts for a large part of cooperation
in our communities. Direct reciprocity arises when repeated interactions occur between the …

Reciprocity is a simple principle for cooperation that explains many of the patterns of how
humans seek and receive help from each other. To capture reciprocity, traditional models …

Humans routinely use conditionally cooperative strategies when interacting in repeated
social dilemmas. They are more likely to cooperate if others cooperated before, and are …

Iterated games constitute an important topic of evolutionary game theory and shape the
human long-run behaviors in social systems. A new class of memory-one strategies for …

Recent theory shows that extortioners taking advantage of the zero-determinant (ZD)
strategy can unilaterally claim an unfair share of the payoffs in the Iterated Prisoner's …

Within the class of memory-one strategies for the iterated Prisoner's Dilemma, we
characterize partner strategies, competitive strategies and zero-determinant strategies. If a …
