Hi, I've a problem with multiple links on the same vertexes. For example we've vertex A and vertex B and we want identify two different edges that they connects to these edges, i.e. A-->B with cost 6 A-->B with cost 8
Is there any way to tag or label these links and using the dijkstra algorithm on the graph?
You want predecessor edges, not predecessor vertices, I assume. You should use the (undocumented) edge_predecessor_recorder visitor (and the record_edge_predecessors() function) instead of predecessor_recorder. -- Jeremiah Willcock
