We address the cooperation problem in structured populations by considering the prisoner’s dilemma game as a metaphor …. In this way, we conclude that in a structured system formed by a growing process, the cooperation evolves if the … theoretical solution of the cooperation problem among genetically unrelated individuals. …

Using both examples and questions they highlight the importance of … structural variations in networks, including differences in the motivations behind network formation; the subsequent development … of networks, including extension, contraction and duration; and the effects of individual decision-makers on network …

We systematically carried out gas–liquid two-phase flow experiments for measuring the time series of flow signals …, which is studied in terms of the mapping from time series to complex networks. In particular, we construct directed weighted … complex networks (DWCN) from time series and then associate different aspects of chaotic dynamics with the topological indices …

This paper proposes a new way to model and analyze contagion in interbank networks. We use a unique dataset from the …, which implies that size is not the sole determinant of importance within networks. Most vulnerable financial institutions …
