dijkstra's shortest path algorithm explained

Below is algorithm based on set data structure.
Below is algorithm based on set data structure.
Initialize distances of all vertices as infinite.
Create an empty set.
Every item of set is a pair. Insert source vertex into the set and make its. distance as 0.
While Set doesn't become empty, do following. Print distance array dist[] to print all shortest.

How does Dijkstra find the shortest route?

Dijkstra's Algorithm

1Mark the ending vertex with a distance of zero.
Designate this vertex as current.
2) Find all vertices leading to the current vertex.
Calculate their distances to the end.
3) Mark the current vertex as visited.
4) Mark the vertex with the smallest distance as current, and repeat from step 2.

How does Dijkstra's shortest path algorithm work?

It starts at the source vertex and iteratively selects the unvisited vertex with the smallest tentative distance from the source.
It then visits the neighbors of this vertex and updates their tentative distances if a shorter path is found.

What is Dijkstra single source shortest path algorithm?

The Dijkstra Shortest Path algorithm computes the shortest path between nodes.
The algorithm supports weighted graphs with positive relationship weights.
The Dijkstra Single-Source algorithm computes the shortest paths between a source node and all nodes reachable from that node.

Dijkstra's algorithm to find the shortest path between a and b. It picks the unvisited vertex with the lowest distance, calculates the distance through it to each unvisited neighbor, and updates the neighbor's distance if smaller.
