WebQuestion: Instructions Use Dijkstra's algorithm to implement a program that computes the shortest distance between two nodes of an undirected weighted graph. Once Dijkstra's algorithm has executed, use its output to automatically identify a shortest path in the graph. Input: - The graph, given by providing in sequence: the number of nodes, then ... 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
