We analyse the effects of agents’ decisions on the creation of congestion on a centralised network with ring-and-hub topology. We show that there are two classes of agents each displaying a distinct set of behaviours. The dynamics of the system are driven by an interplay between the formation...

Games constitute a research domain that is attracting the interest of scientists from numerous disciplines. This is … intelligence in games (CIG). This network has been constructed from bibliographical data obtained from the Digital Bibliography … other features. Overall, computational intelligence in games exhibits similarities with other collaboration networks such as …

We introduce the vertex weight into the spatial prisoners’ dilemma game to investigate the evolution of cooperation … the exponential, power-law and uniform ones. Compared with the traditional version, we find that the cooperation level is … markedly enhanced under the weighted square lattice. For most ranges of b, the highest cooperation level can be obtained under …

A fundamental question of human society is the evolution of cooperation. Many previous studies explored this question ….e., integrating neighborhoods in the evaluation of fitness, promotes cooperation. If we enhance the value of u, the invasion of … influence of the environment on the evolution of cooperation. Finally, the universality of this mechanism is testified for …

In this paper, we study an aspiration-induced migration model, in which each individual plays the prisoner’s dilemma game with those being within a circle of radius r centered on himself/herself. An individual will migrate to a randomly chosen place with the velocity v if his/her payoff is...

The basic difficulty in cooperation theory is to justify the cooperation. Here we propose a new approach, where players … are driven by their altruism to cooperate or not. The probability of cooperation depends also on the co …-player’s reputation. We find that players with positive altruism cooperate and meet cooperation. In this approach, payoffs are not …
