Human societies are organized in complex webs that are constantly reshaped by a social dynamic which is influenced by the information individuals have about others. Similarly, epidemic spreading may be affected by local information that makes individuals aware of the health status of their social contacts, allowing them to avoid contact with those infected(More)
Designing an adaptive multi-agent system often requires the specification of interaction patterns between the different agents. To date, it remains unclear to which extent such interaction patterns influence the dynamics of the learning mechanisms inherent to each agent in the system. Here, we address this fundamental problem, both analytically and via(More)
Whether by nature or nurture, humans often respond differently when facing the same situation. Yet, the role of behavioral differences between individuals when immersed in their social network remains largely ignored in most problems of natural and social sciences. Here, we investigate how diversity in the way individuals assess their adverse social(More)
— Humans are inclined to engage in long-lasting relationships whose stability does not only rely on cooperation, but often also on loyalty — our tendency to keep interacting with the same partners even when better alternatives exist. Yet, what is the evolutionary mechanism behind such irrational behavior? Furthermore, under which conditions are individuals(More)
Cooperation is essential in every society, but puzzling from an evolutionary perspective. Here, we discuss the work published in [11], where we address the role of behavioral differences — ubiquitous among Humans — in the evolution of cooperation. We study a model in which individuals interact along the edges of a complex network, engaging in social(More)
Throughout their life, humans often engage in public goods games in situations ranging from family related issues to global warming. In all cases, the tragedy of the commons threatens the possibility of reaching the optimal solution associated with global cooperation. Up to now, individuals have been treated as equivalent in all respects, in sharp contrast(More)
There is variability in the cancer phenotype across individuals: Two patients with the same tumor may experience different disease life histories, resulting from genetic variation within the tumor and from the interaction between the tumor and the host. Up to now, phenotypic variability has precluded a clear-cut identification of the fundamental(More)
