| Abstract: | In this paper, we introduce a modified small-world network added withnew links with preferential connection instead of adding randomly,then we apply Bak-Sneppen (BS) evolution model on this network.Several dynamical character of the model such as the evolutiongraph, f0 avalanche, the critical exponent D and τ, andthe distribution of mutation times of all the nodes, showparticular behaviors different from those of the model based onthe regular network and the small-world network. |
