WebMar 20, 2024 · Below are the detailed steps used in Dijkstra’s algorithm to find the shortest path from a single source vertex to all other vertices in the given graph. Algorithm 1) Create a set sptSet (shortest path tree set) that keeps track of vertices included in shortest path tree, i.e., whose minimum distance from source is calculated and finalized. WebMay 13, 2024 · 1) Initialize distances of all vertices as infinite. 2) Create an empty priority_queue pq. Every item of pq is a pair (weight, vertex). Weight (or distance) is used used as first item of pair as first item is by default used to compare two pairs 3) Insert source vertex into pq and make its distance as 0.
