WebAug 2, 2024 · Dijkstra’s Algorithm basically starts at the node that you choose (the source node) and it analyzes the graph to find the shortest path between that node and all the other nodes in the graph. WebIt is important to note the following points regarding Dijkstra Algorithm-. Dijkstra algorithm works only for connected graphs. Dijkstra algorithm works only for those graphs that do not contain any negative weight edge. The actual Dijkstra algorithm does not output the shortest paths. It only provides the value or cost of the shortest paths.
