Recent experimental results with humans involved in social dilemma games suggest that cooperation may be a contagious phenomenon and that the selection pressure operating on evolutionary dynamics (i.e., mimicry) is relatively weak. I propose an evolutionary dynamics model that links these experimental findings and evolution of cooperation. By assuming a small fraction of (imperfect) zealous cooperators, I show that a large fraction of cooperation emerges in evolutionary dynamics of social… 
Critical mass effect in evolutionary games triggered by zealots
TLDR
It is found that a tipping point exists in coordination games, whereas the same phenomenon depends on the selection pressure, update rule, and network structure in other types of games.
Evolutionary dynamics in finite populations with zealots
TLDR
It is shown that in the case without zealots, there is a threshold selection intensity below which the fixation is fast for an arbitrary payoff matrix, and in this scenario the fixation time is exponentially long in terms of the population size.

Effect of spatial structure on the evolution of cooperation based on game models
To elucidate the mechanisms for the evolution of cooperation has been a core problem in biology, economics and sociology. Evolutionary game theory has proven to be an efficient approach to
MATHEMATICAL ENGINEERING TECHNICAL REPORTS Evolutionary Dynamics in Finite Populations with Zealots
TLDR
It is shown that in the case without zealots, there is a threshold selection intensity below which the fixation is fast for an arbitrary payoff matrix, and in this scenario the fixation time is exponentially long in terms of the population size.
Individualised aspiration dynamics: Calculation by proofs
TLDR
This work proves that the evolutionary outcome with heterogeneous aspirations is the same as that of the homogeneous one for regular networks under weak selection limit, and indicates that self-evaluation processes are robust in contrast with comparison based rules.

Effect of Strategy-Homogeneity on the Prisoner’s Dilemma Game in a Square Lattice
We investigate the effect of strategy-homogeneity on the prisoner’s dilemma game in a square lattice. Strategy-homogeneity means that the population contains at least one connected group in which
Emergence of Cooperation in Complex Agent Networks Based on Expectation of Cooperation: (Extended Abstract)
TLDR
This paper proposes a behavioral strategy called expectation of cooperation strategy with which cooperation in the prisoner's dilemma game emerges in agent networks by incorporating Q-learning and results indicate that cooperation emerged.

Emergence of cooperation and evolutionary stability in finite populations
TLDR
It is shown that a single cooperator using a strategy like ‘tit-for-tat’ can invade a population of defectors with a probability that corresponds to a net selective advantage.
Wisdom of groups promotes cooperation in evolutionary social dilemmas
TLDR
A dynamically decelerated invasion process is revealed, by means of which interfaces separating different domains remain smooth and defectors therefore become unable to efficiently invade cooperators and establishes decentralized decision making as very beneficial for resolving social dilemmas.
Human strategy updating in evolutionary games
TLDR
This work presents a way to measure properties of the update mechanisms used in theoretical models of cultural evolution in a behavioral experiment and finds that spontaneous strategy changes corresponding to mutations or exploration behavior are more frequent than assumed in many models.

TLDR
In this model, cooperators and defectors interact as in the classical prisoner's dilemma, but here the presence of a small number of cooperation facilitators enhances the fitness (reproductive potential) of cooperators, while it does not alter that of defectors.
Spatial structure often inhibits the evolution of cooperation in the snowdrift game
TLDR
The results caution against the common belief that spatial structure is necessarily beneficial for cooperative behaviour, and show that no such general predictions can be made for the effects of spatial structure in the snowdrift game.
Cooperation among non-relatives evolves by state-dependent generalized reciprocity
TLDR
It is shown that cooperation can evolve by generalized reciprocity (help anyone, if helped by someone) even in large groups, if individuals base their decision to cooperate on a state variable updated by the outcome of the last interaction with an anonymous partner.
Contingent movement and cooperation evolve under generalized reciprocity
TLDR
It is shown that cooperation may be evolutionarily stable if decisions taken to cooperate and to change group membership are both dependent on anonymous social experience (generalized reciprocity), and that mechanisms of assortment within populations are often behavioural decisions and should not be considered independently of the evolution of cooperation.
Stochastic dynamics of invasion and fixation.
TLDR
A simple closed formula is derived that determines the feasibility of cooperation in finite populations, whenever cooperation is modeled in terms of any symmetric two-person game, and is valid at all intensities of selection and for any initial condition.
