Remove all edges specified in ebunch. Hi, igraph does not allow duplicate nodes either, the difference is that igraph nodes are identified by a numeric ID and not by a string label ;) (Otherwise it would be impossible to import graphs from GraphML files containing two nodes with the same name). Suppose that we have a large graph with nearly 100 million edges and around 5 million nodes, in this case what is the best graph mining platform that you know of that can give all simple paths of lengths <=k (for k=3,4,5) between any two given nodes. # __docformat__ = "restructuredtext en" from copy import deepcopy import matplotlib.
