Random Barabási–Albert network

Python

random_barabasi_albert_graph[vert_type](   n: int, p: float, random_state) -> undirected_network[vert_type]

C++

template<integer_network_vertex VertT, std::uniform_random_bit_generator Gen>
undirected_network<VertT> random_barabasi_albert_graph(VertT n, VertT m, Gen &generator)

Generates a random Barabási–Albert network [3] of size n, vertices are added one-by-one and each vertex is connected to m random existing vertices.

The parameter m needs to be smaller than n and larger than or equal to 1, otherwise the function fails by raising a ValueError exception in Python or a std::invalid_argument exception in C++.
