Can dijkstra work on undirected graph

WebJan 18, 2024 · Unfortunately, standard low-diameter decomposition algorithms only work on undirected graphs — those in which every edge can be traversed in both directions. The negative-weight shortest-paths problem, meanwhile, only makes sense on directed graphs, in which every edge is a one-way street. WebDijkstra's algorithm can be used to find the shortest path on both directed and undirected graphs due to its greedy strategy. Dijkstra's algorithm can be implemented by representing the input graph in the form of an adjacency list and …
