gnc_graph(n, create_using=None, seed=None)[source]

Return the GNC digraph with n nodes.

The GNC (growing network with copying) graph is built by adding nodes one at a time with a links 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.
