A Multilevel Simplification Algorithm for Computing the Average Shortest-Path Length of Scale-Free Complex Network by Guoyong Mao, Ning Zhang

“…Computing the average shortest-path length (ASPL) of a large scale-free network needs much memory space and computation time. Based on the feature of scale-free network, we present a simplification algorithm by cutting the suspension points and the connected edges; the ASPL of the original network can be computed through that of the simplified network. …”
