TL;DR: In this article, the authors proposed a model of evolutionary snowdrift game with $N$-person interactions and studied the effects of multi-person interaction on the emergence of cooperation, showing that the extent of cooperation drops with increasing cost-to-benefit ratio and the number of interaction persons in a group.

TL;DR: In this article, a model of evolutionary snowdrift game with N-person interactions was proposed and the effects of multi-person interaction on the emergence of cooperation was studied, and an exact N-thorder equation for the equilibrium density of cooperators x* was derived for a well-mixed population using the approach of replicator dynamics.

TL;DR: A model of weighted scale-free networks incorporating a stochastic scheme for weight assignments to the links, taking into account both the popularity and fitness of a node is proposed, demonstrating a power-law distribution with an exponent sigma that depends on the probability p.

TL;DR: The effects of networking on the extent of cooperation emerging in a competitive setting are studied and it is found that the standard deviation of the degree distribution is the dominant network property that governs the extinction payoffs.

TL;DR: The dynamical process of opinion formation within a model using a local majority opinion updating rule is studied numerically in networks with the small-world geometrical property, showing the effects of having shortcuts in a lattice of fixed spatial dimension to be analogous to that of increasing the spatial dimension in regular lattices.
