This article evaluates the maximum data flow from a sender to a receiver via the internet when all transmissions are scheduled for early morning hours. The significance of early morning hours is that internet congestion is low while users sleep....

Searching for a Single Community in a Graph
Avik Ray, Sujay Sanghavi, Sanjay Shakkottai
Article No.: 13
DOI: 10.1145/3200863

In standard graph clustering/community detection, one is interested in partitioning the graph into more densely connected subsets of nodes. In contrast, the search problem of this article aims to only find the nodes in a single such...
