The problem of finding relatively highly dense sub-structures in various social networks such as communication networks, collaboration networks and web networks has received a lot of attention [Gol84,Cha00,GKT05,KP93,Law01]. Experiments have suggested that such subgraphs correspond to communities in those networks. Formally, given an undirected un-weighted graph, the problem is to find the densest subgraph of the given graph.

The combinatorial algorithms based on max flow computation for finding maximum density subgraphs have been studied extensively [Gol84,Law01]. However, the time complexity of exactly finding the densest component using these algorithms is cubic or worse, and hence, they are not scalable for large graphs in real-world settings. Although the previous stated results are the best that any deterministic algorithm can achieve, there exist fast linear time algorithms for computing approximate solutions [Cha00,KP93]. However, they are destructive and, thus, return only a single subgraph.
