WebOct 17, 2024 · The most common example of Dijkstra’s algorithm in the wild is in path-finding problems, like determining directions or finding a route on GoogleMaps. Dijkstra’s algorithm implemented for path ... WebThis algorithm is also efficient, meaning that it can be implemented in a reasonable amount of time. Dijkstra’s algorithm takes around V2 calculations, where V is the number of vertices in a graph. A graph with 100 vertices would take around 10,000 calculations. While that would be a lot to do by hand, it is not a lot for computer to handle.
