Local Density Sven

We survey computational approaches and solutions for discovering locally dense groups in social and complex networks. A graph-theoretical property is local if it is definable over subgraphs induced by the groups only. In this context, we discuss perfectly dense groups (cliques), structurally dense groups (plexes, cores), and statistically dense groups (η-dense groups). We give algorithms (and h...

The main idea is to have two or more persons at different locations, who can interact with each other in the same virtual environment.
