WebBy unweighted graphs I assume you mean a constant weight of (say) 1 per edge. Otherwise it is unclear what a shortest path might mean. Dijkstra's algorithm works for positive real-valued weights, while Thorup's algorithm requires positive integer weights. Thus both will work for constant edge weight problems. – Dec 3, 2014 at 4:04 4 WebSep 5, 2024 · This algorithm allows finding the shortest path between one node and every other node in either a directed or undirected graph with non-negative weights.
