The classical dynamics on an Erdos-Renyi network with the wiring probability $p_{ER} le frac{1}{N}$ is in the state of collective order, while that on an Erdos-Renyi network with $p_{ER} > frac{1}{N}$ in the state of collective chaos. The dynamics on a WS Small-world complex network evolves from collective order to collective chaos rapidly in the region of the rewiring probability $p_r in [0.0,0.1]$, and then keeps chaotic up to $p_r = 1.0$. The dynamics on a Growing Random Network (GRN) is in a special state deviates from order significantly in a way opposite to that on WS small-world networks. Each network can be measured by a couple values of two parameters $(eta ,eta)$. | | Source: | arXiv, cond-mat/0505086 | | Services: | Forum | Review | PDF | Favorites | |
