n and m are the total number of nodes and edges, respectively. <k> is the average degree for undirected networks or the average out-degree for directed networks. kmax is the maximum degree for undirected networks or the maximum out-degree for directed networks. <c> is the average clustering coefficient and H is the degree heterogeneity, defined as Inline graphic45.
