dijkstra algorithm complexity analysis
What is the complexity of Dijkstra adjacency matrix?
For Dijkstra Algorithm using matrix representation, the time complexity is O(V^2).
But for list representation, the time complexity is O((V+E)Log(V)).What is the complexity of Dijkstra's algorithm?
Assume the source vertex = .
Time Complexity of Dijkstra's Algorithm is O ( V 2 ) but with min-priority queue it drops down to O ( V + E l o g V ) .What is the complexity of the shortest path?
Single-source shortest path is solved by the Bellman-Ford algorithm, with a time complexity of O(VE).
All-pairs shortest path can be solved using Johnson's algorithm in O(EV + V2 log V) time.
Additionally, there is the Floyd-Warshall algorithm, which solves it in O(V3): this is typically faster on dense graphs.Dijkstra's algorithm is used to find the shortest path between the two mentioned vertices of a graph by applying the Greedy Algorithm as the basis of principle.
For Example: Used to find the shortest between the destination to visit from your current location on a Google map.
