"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. " - Dijkstra's algorithm example

WebMar 27, 2024 · Dijkstra’s algorithm is a greedy algorithm that solves the single-source shortest path problem for a directed and undirected graph that has non-negative edge weight. For Graph G = (V, E) w (u, v) ≥ 0 for each edge (u, v) ∈ E. This algorithm is used to find the shortest path in Google Maps, in network routing protocols, in social ... WebNov 8, 2024 · Dijkstra The worst-case time complexity depends on the graph’s sparsity and the data structure to implement . For example, in dense graphs, , and since Dijkstra checks each edge twice, its worst-case time complexity is also . However, if the graph is sparse, is not comparable to . With a Fibonacci heap as , the time complexity becomes .
