gnc_graph

gnc_graph(n, create_using=None, seed=None)

Return the growing network with copying (GNC) digraph with n nodes.

The GNC graph is built by adding nodes one at a time with a link to one previously added node (chosen uniformly at random) and to all of that node’s successors.

Parameters:

• n (int) – The number of nodes for the generated graph.
• create_using (graph, optional (default DiGraph)) – Return graph of this type. The instance will be cleared.
• seed (hashable object, optional) – The seed for the random number generator.
