WebMay 12, 2012 · Dijkstra's algorithm returns a shortest path tree, containing the shortest path from a starting vertex to each other vertex, but not necessarily the shortest paths between the other vertices, or a shortest route that visits all the vertices. Here's a counter example where the greedy algorithm you describe will not work: WebNov 21, 2016 · 1. Dijkstra's algorithm works with weighted graphs to compute the shortest path from a vertex to all other vertices in a graph provided there are no negative edge lengths in the graph. So there is no need to change the implementation of Dijkstra's to make it work with weighted graph. If it doesn't work with weighted graph then the problem lies ...

WebNov 29, 2024 · The Dijkstra algorithm is an algorithm used to solve the shortest path problem in a graph. This means that given a number of nodes and the edges between them as well as the “length” of the edges (referred to as “weight”), the Dijkstra algorithm is finds the shortest path from the specified start node to all other nodes. Nodes are sometimes … WebDijkstra's Algorithm. Dijkstra algorithm is a single-source shortest path algorithm. Here, single-source means that only one source is given, and we have to find the shortest path from the source to all the nodes. Let's …
