graph theory - Variants of Densest Subgraph Problems

WebbDense subgraph discovery is an important primitive for many real-world applications such as community detection, link spam detection, distance query indexing, and computa-tional biology. In this thesis, our focus is on solving the densest subgraph problem - ﬁnding a subgraph with the highest average degree in a graph.
