It is well known that cooperation cannot be an evolutionarily stable strategy for a non-iterative game in a well-mixed population. In contrast, structured populations favor cooperation, since cooperators can benefit each other by forming local clusters. Previous studies have shown that scale-free networks strongly promote cooperation. However, little is known about the invasion mechanism of cooperation in scale-free networks. To study microscopic and macroscopic behaviors of cooperators… 
Hierarchical invasion of cooperation in complex networks
TLDR
The invasion of cooperation will succeed only when the initial cooperators are numerous enough to form a cluster from which cooperation can spread, which implies that the initial condition has to be a suitable equilibrium between high degree and high numerosity.
How mutation alters fitness of cooperation in networked evolutionary games
TLDR
The analyses revealed that mutation always has a negative effect on the evolution of cooperation regardless of the fraction of cooperators and network structures, and it was found that mutation affects the fitness of cooperation differently on different social network structures.
Degree of Satisfaction-based Adaptive Interaction in Spatial Prisoner's Dilemma
To study why the altruistic cooperation behavior can emerge and maintain among egoistical individuals, researchers across several disciplines have made great contributions for the solutions of this
Social Pressure and Environmental Effects on Networks: A Path to Cooperation
TLDR
This paper considers a known model where agents play a Prisoner's Dilemma Game among themselves and the pay-off matrix of an individual changes according to the number of neighbors that are “vigilant”, i.e., how many neighbors watch out for her behavior, and finds which situations the vigilance by the others is more effective in favoring cooperative behaviors and when its influence is weaker.
The effect of memory in prisoner’s dilemma game under multi-strategy update mechanism
TLDR
The memory factor is introduced into the game model, and the joint effect of memory and heterogeneous strategy updating rules on the emergence of cooperation is studied, shedding some light to the role of memory in prisoner’s dilemma game under heterogeneous strategies updating rules.
Trust-based partner switching among partitioned regions promotes cooperation in public goods game
TLDR
The coevolution mechanism of trust-based partner switching among partitioned regions on an adaptive network is studied and it is found that the influence of vigilance increasing against unsatisfactory behavior on evolution direction depends on the level of cooperation reward.
Research on an evolutionary game model and simulation of a cluster innovation network based on fairness preference
TLDR
This paper constructs an evolutionary game model of a cluster innovation network based on a spatial public goods game and the theory of fairness preferences, which involves the processes of investment and payoff allocation and aims to improve the overall cooperation level and cooperation income of the network.

Coevolutionary Games - A Mini Review
A new route to the evolution of cooperation
TLDR
It is shown that cooperators are capable of exploring the heterogeneity of the population structure to become evolutionary competitive and cooperation becomes the dominating trait in scale‐free networks of contacts in which the few highly connected individuals are directly inter‐connected, in this way contributing to self‐sustain cooperation.
The Emergence of Cooperation in Public Goods Games on Randomly Growing Dynamic Networks
TLDR
This work presents a coevolutionary model of public goods games in networks, growing by random attachment, from small founding populations of simple agents, and demonstrates the emergence of cooperation in moderately heterogeneous networks, regardless of original founders' behaviour, and absent higher cognitive abilities such as recognition or memory.
Participation costs dismiss the advantage of heterogeneous networks in evolution of cooperation

TLDR
In replicator-type evolutionary dynamics, it is shown that even a relatively small participation cost extinguishes the merit of heterogeneous networks in terms of cooperation.

Evolution of Cooperation in a Heterogeneous Graph: Fixation Probabilities under Weak Selection
TLDR
A new state variable is introduced to measure the time evolution of cooperation in a heterogeneous graph and it is found that the fixation probability of a single cooperator depends crucially on the number of its neighbors.
Emergence of cooperative linkages by random intensity of selection on a network
Scale-free networks provide a unifying framework for the emergence of cooperation.
TLDR
It is found that, whenever individuals interact following networks of contacts generated via growth and preferential attachment, cooperation becomes the dominating trait throughout the entire range of parameters of both games, as such providing a unifying framework for the emergence of cooperation.
A simple rule for the evolution of cooperation on graphs and social networks
TLDR
A surprisingly simple rule is described that is a good approximation for all graphs that are analysed, including cycles, spatial lattices, random regular graphs, random graphs and scale-free networks: natural selection favours cooperation if the benefit of the altruistic act, b, exceeds the average number of neighbours, k, which means b/c > k.
