That said, I assume add_edge does add the nodes if they do not exist in the graph when the edge is added and that when an edge is added and one or both nodes exist it uses them, since the code works and I appear to be getting the correct answers.
You're right, sorry to misinform you. From the documentation: "if either vertex descriptor u or v (which are integers) has a value greater than the current number of vertices in the graph, the graph is enlarged so that the number of vertices is std::max(u,v) + 1.
