The igraph library for complex network research     igraph is a free software package for creating and manipulating undirected and directed graphs. It includes implementations for classic graph theory problems like minimum spanning trees and network flow, and also implements algorithms for some recent network analysis methods, like community structure search     http://igraph.sourceforge.net/index.html     tags: python igraph clustering Introduction to Information Retrieval     This is the companion website for the following book.
