-free networks embedded by the suggested algorithm are studied both analytically and through simulations. Our findings indicate … dramatic changes in the embedded networks, in comparison to their off-lattice counterparts, and call into question the … applicability of off-lattice scale-free models to realistic, everyday-life networks. …

in Erdős–Rényi (ER) and random scale free (SF) networks, with degree distribution P(k)=ck−λ. We show that the chemical … dimension is dl=2 for ER and SF networks with λ>4, as in percolation in d⩾dc=6 dimensions. For 3<λ<4 we show that dl=(λ−2)/(λ−3 …)/(λ−3) (3<λ<4). We discuss the meaning of these dimensions for networks. …

Tuning u equal to zero returns the ….e., integrating neighborhoods in the evaluation of fitness, promotes cooperation. If we enhance the value of u, the invasion of …

Based on extensive … the multiplication factor. We attribute the enhancement of cooperation to the inherited fitness that stabilizes the …

's fitness is not characterized by a single number but by M traits. Each trait represents one aspect of the competitiveness of … regulations decreases with increasing M, i.e., size-based regulations are less effective when the overall fitness of a firm is …

Most real-world networks from various fields share a universal topological property as community structure. In this … paper, we propose a node-similarity based mechanism to explore the formation of modular networks by applying the concept of … hidden metric spaces of complex networks. It is demonstrated that network community structure could be formed according to …

For the firm fitness evolution, we take into account a constraint such … that the disappearance of a firm modifies the fitness of nearest-neighboring ones, as in Bak–Sneppen population fitness …
