Note that it is important to have all shortest paths registred, not just one, as seen in many Bellman-Ford/Dijkstra implementations (for instance Graph.shortest_path_all_pairs or networkx.algorithms.shortest_paths.all_pairs_shortest_path), and not just a number of those paths.
I am also satisfied with only a list of "optimal" predecessors... as long as the list is complete.
Thank you for answers!MorgothTue, 09 Jul 2013 00:45:53 -0500https://ask.sagemath.org/question/10332/
