"Web1 day ago · I know about the Prufer sequence. However, as far as I know, it's implemented for trees. Thus, Prufer sequence can't preserve the weight and directions of our edges in the graph. Maybe there exist an algorithm that performs a deterministic walk of any graph (leading to 1 path for any given graph). Any help/direction would be greatly appreciated. " - Graph.get_shortest_paths
