  • Published 2006
In the Densest k-Subgraph problem (DSP), we are given an undirected weighted graph G = (V, E) with n vertices (v1, ..., vn). We seek to find a subset of k vertices (k belonging to {1, ..., n}) which maximizes the number of edges which have their two endpoints in the subset. This problem is NP-hard even for bipartite graphs, and no polynomial-time algorithm with a fixed performance guarantee is known for the general case. Several authors have proposed randomized approximation algorithms for… CONTINUE READING
