TL;DR: This study shows that when a network becomes assortative mixing by degree, the large-degree vertices tend to interconnect to each other closely, which destroys the sustainability among cooperators and promotes the invasion of defectors, whereas in disassortative networks, the isolation among hubs protects the cooperative hubs in holding onto their initial strategies to avoid extinction.

TL;DR: A novel decentralized adaptive pinning-control scheme for cluster synchronization of undirected networks using a local adaptive strategy on both coupling strengths and feedback gains is proposed.

TL;DR: In this article, the authors investigated the effect of individual heterogeneity by setting the cooperator x an investment value correlated to its degree, where x = N ⋅ k x β / ∑ j k j β, where k x is the degree of x, j runs over all players and β is a tunable parameter.

TL;DR: It is found that the assortative mixing among the individuals inhibits the emergence and sustainment of the cooperation, due to fact that the distinct core-periphery structure present in theAssortative networks disable the hubs's ability to impact those remote leaf-vertices, and as a result the defection is easy to diffuse among them.

TL;DR: An evolutionary spatial prisoner's dilemma game where the fitness of the players is determined by both the payoffs from the current interaction and their history and another factor to promote cooperation is a diversity of reproduction time scales.
