WebTrue or false: For graphs with negative weights, one workaround to be able to use Dijkstra’s algorithm (instead of Bellman-Ford) would be to simply make all edge weights positive; for example, if the most negative weight in a graph is -8, then we can simply add +8 to all weights, compute the shortest path, then decrease all weights by -8 to return to the … Web2 Answers. Although simple to implement, Dijkstra's shortest-path algorithm is not optimal. A guaranteed linear time, linear space (in the number of edges) algorithm is referenced by the Wikipedia article Shortest path problem as: Thorup, Mikkel (1999) "Undirected single-source shortest paths with positive integer weights in linear time".
