Network Modeling Software

This software is a set of NetworkX additions for the creation of graphs to model networks.

• Graphicality Testing -- This is a set of routines for testing if a sequence is graphical, multi-graphical, or pseudo-graphical.  All tests are performed in linear time.  It also tests whether an input and output sequence has a directed realization.  These routines are independent of NetworkX.
  
• Bipartite Graph Generator -- This is a routine for generating a bipartite graph whose projection is a given graph.  Based on the algorithm of Guillaume and Latapy.
• Sequential Graph Generator -- A routine for sequentially generating a graph from a given degree sequence.  Based on the algorithm of Blitzstein and Diaconis.
• Markov Graph Generator -- Set of helper routines for generating a graph from a given degree sequence using a Markov sampling approach.  Based on the paper of Gkantsidis, Mihail, and Zegura.
• Network Modeling Toolkit  -- A graphical front end for creating network models.
