WebFeb 7, 2024 · 4. Dijkstra’s Algorithm. This algorithm might be the most famous one for finding the shortest path. Its advantage over a DFS, BFS, and bidirectional search is that you can use it in all graphs with positive edge weights. Don’t try it on graphs that contain negative edge weights because termination is not guaranteed in this case. hanseat gmbh

WebSep 28, 2024 · With Dijkstra's Algorithm, you can find the shortest path between nodes in a graph. Particularly, you can find the shortest path from a node (called the "source node") to all other nodes in the graph, producing a shortest-path tree. This algorithm is used in GPS devices to find the shortest path between the current location and the destination.
