  Social networks have a scale-free property and community structure, and many
problems in life have the characteristic of public goods, such as resource
shortage. Due to different preferences of individuals, there exist individuals
who adopt heterogeneous strategies updating rules in the network. We
investigate the evolution of cooperation in the scale-free community network
with public goods games and the influence of multiple strategy updating rules.
Here, two types of strategy updating rules are considered which are pairwise
comparison rules and aspiration-driven rules. Numerical simulations are
conducted and presented corresponding results. We find that community structure
promotes the emergence of cooperation in public goods games. In the meantime,
there is a "U" shape relationship between the frequency of cooperators and the
proportion of the two strategy updating rules. With the variance in the
proportion of the two strategy updating rules, pairwise comparison rules seem
to be more sensitive. Compared with aspiration-driven rules, pairwise
comparison rules play a more important role in promoting cooperation. Our work
may be helpful to understand the evolution of cooperation in social networks.
