Generating Barabasi graphs with predefined initial graph #132

Closed ntamas closed 4 years ago

Suppose I have a graph G and I want to add N nodes to it using preferential attachment. Is it possible to use ig.Graph.Barabasi to do this (example: ig.Graph.Barabasi(N, M, initial_graph=G))?

Yes, but 1) you need to specify N plus the vertex count of the original graph and 2) you need start_from and not initial_graph.
