WebNov 20, 2024 · Dijkstra's Algorithm is one of the most popular algorithms in graph theory. It is used to find the shortest path between any two vertices of a weighted, non-negative, and directed graph. It uses the greedy approach where the shortest path is chosen. The algorithm keeps track of the currently known shortest distance from each node to the … 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 ...
