%X Technical The structure of interaction plays an important role in
the outcome of evolutionary games. This study investigates the evolution
of stochastic strategies of the pris- oner's dilemma played on structures
ranging from lattices to small world networks.Strategies and payos
are analyzed as a function of the network characteristics of the
node they are playing on. Nodes with lattice-like neighbourhoods
tend to perform better than the nodes modied during the rewiring
process of the construction of the small-world network. Non-technical
Studies of the prisoners dilemma played on small-world networks have
shown that the population average score decreases as the probability
of rewiring is in- creased, leading to the conclusion that a small-world
network structure does not favor cooperation. This study shows that
the decrease of the average score is not a population-level phenomenon
and is caused by only a minority of the population, suggesting that
the small-world structure does not a ect the dynamics of all nodes
in a network uniformly. This result has implications for understanding
the complex dynamics of real-world collaboration networks.
