Although much attention was paid in the theoretical literature in the thermo- dynamical limit (when time and number of nodes tend to ∞) in these models, not too much is known for graphs with a bound in their size ([11] being an interesting exception). Indeed, many of the computer-...
This leads to a time complexity of O(|V ||E|), which is impractical for large graphs. Estimation of betweenness centrality has focused on performing shortest-path calculations on a subset of randomly-selected vertices. This reduces the complexity of the centrality estimation to O(|S||E|), ...

Efficient embedding of scale-free graphs in the hyperbolic plane. This is an interesting paper from the graph embedding domain. Graph embedding deals with mapping the vertices of a graph to points in a space such that the metric distance in that space between vertices corresponds to actual edges...
