Notre Dame networks, A. Barabasi.
================================================================================
The NotreDame_actors, _www, and _yeast networks were derived from
the Pajek versions of the networks. Details below.

Converted to sparse adjacency matrix format by Tim Davis, October 2006.
A(i,j) is the edge from node i to node j in the graph. If a graph is not
listed as weighted, and yet has non-binary entries, then the entry a(i,j)
reflects the number of edges (i,j) in the original data (the graph is a
multigraph).
All data was converted without loss of information, except where intentional.
Details are given below.
"Pajek" is Slovenian for "spider" and is roughly pronounced "Pie yeck".
The Pajek networks are all 1-based (nodes are numbered starting at node 1).

Description
Notre Dame Self-Organized Networks:
1. NDwww.net directed network with 325729 vertices and 1497135 arcs (27455
loops); page X is linked to page Y.
2. NDactors.net undirected two-mode network with 520223 vertices (392400
players, 127823 movies) and 1470418 edges; player X plays in movie Y.
3. NDyeast.net undirected network with 2114 vertices and 2277 edges (74
loops); protein X interacts with protein Y.
NDwww.net (ZIP, 2050K) NDactors.net (ZIP, 4150K) NDyeast.net (ZIP, 7K)
Background
The networks ND*.net are based on the files from Notre Dame Self-Organized
Networks Database. To transform the data into Pajek format: vertex 0 was
replaced by the vertex number equal to the number of vertices in a network;
Pajek keywords were inserted; and the network was saved in the short (as lists
of neighbors) format.

large networks with Pajek?
2. Actor: Actor network data: (based on www.imdb.com) In the original ND
network file: each line corresponds to one movie, each number represents actor:
number_1 number_2 ... number_k (k actors who play in the same movie).

protein interaction network of yeast. Edges: From protein -> To protein. For
