The problem has received a great deal of attention in the algorithmic literature over the last five decades, with many variants proposed and many applications built on top of this basic definition.

WebbDetermining the optimal feature set is a challenging problem, especially in an unsupervised domain. To mitigate the same, this paper presents a new unsupervised feature selection method, termed as densest feature graph augmentation with disjoint feature clusters. The proposed method works in two phases. The first phase focuses on finding the maximally … WebbDensest subgraph problem (DSG) and the densest subgraph local decomposition problem.

Recall that the Planted Clique conjecture is that there is no polynomial time algorithm that distinguishes random graphs with graphs that have a planted -clique. Hence, 1. PC is a special (average) case of the 1 2-v.s.-1 Densest- -Subgraph problem. 2.
