Cooperation is ubiquitous in every level of living organisms. It is known that spatial (network) structure is a viable mechanism for cooperation to evolve. Until recently, it has been difficult to predict whether cooperation can evolve at a network (population) level. To address this problem, Pinheiro et al. proposed a numerical metric, called Average Gradient of Selection (AGoS) in 2012. AGoS ...

Cooperation plays a key role in the evolution of complex systems. However, the level of cooperation extensively varies with the topology of agent networks in the widely used models of repeated games. Here we show that cooperation remains rather stable by applying long-term learning + innovative strategy adoption rules on a variety of random, regular, small-word, scale-free and modular networks ...

The recent advances in cooperative relaying in wireless systems and the development of "distributed" MIMOs have established the benefits of cooperation at the physical layer. However, it is possible to extend the notion of cooperation at the network level where simple protocol features can achieve substantial benefits on top of those that traditional cooperative techniques do. In this talk we w...
