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. …

some observations about the analysis of social networks. 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 …

social network data collection and analysis in recent years. Within many such networks the interactions are transient: thus … those networks evolve over time. In this paper we introduce a class of models for such networks using evolving graphs with … memory dependence. In particular we show that such networks may continue evolving forever, or else may quench and become …
