A selfish routing game is a simple model of selfish behaviors in networks. It is called that Braess’s paradox occurs in the selfish routing game if an equilibrium flow achieved by players’ selfish behaviors is not the optimal minimum latency flow. In order to make the minimum latency flow a Nash equilibrium, a marginal cost tax has been proposed. Braess(More)
In this paper, we propose multi-population replicator dynamics with changes of players’ interpretations. We consider that each population has various interpretation functions and choose one of them depending on payoffs. We propose a model representing changes of the interpretation functions according to the payoffs. Moreover, we apply our proposed model to(More)
It is known that the optimal sensor coverage of a mission space is performed by the Voronoi coverage. Aside from the energy required to move, communication among sensors consumes a large amount of their limited energy. So, to reduce communication energy, we propose a distributed control method that deploys sensors avoiding the obstacles by means of(More)
In social and biological systems, there exist many populations which consist of a large number of selfish players interacting with each other. In such a population, the purpose of each player often conflicts with the total purpose of the population, and a problem such as a social dilemma occurs. To resolve the problem, a government sometimes tries to(More)
Recently, there has been an increased reliance on computing systems supported by a multi-tier architecture. In multi-tier computing systems, it is important to appropriately manage resource allocation to ensure fairness of a QoS (Quality of Service) level avoiding overload conditions in tiers. This paper proposes an adaptive resource management algorithm(More)
