Currently, community detection has led to a huge interest in data analysis on real-world networks. However, the high computationally demanding of most community detection algorithms limits their applications. In this paper, we propose a heuristic algorithm to extract the community structure in large networks based on local community attractive force optimization whose time complexity is near linear...
We study survivable broadcast in high-speed networks against a single link/node failure. We follow the classic approach of blue/red tree [1] to construct a pair of spanning trees (i.e. a blue tree and a red tree) such that the connectivity between the root and an arbitrary node is ensured (via at least one tree) in the presence of a single link/node failure. To ensure that the blue and red trees are...
