WebMar 16, 2024 · Below is algorithm based on set data structure. 1) Initialize distances of all vertices as infinite. 2) Create an empty set. Every item of set is a pair (weight, vertex). Weight (or distance) is used as first item of pair as first item is by default used to compare two pairs. 3) Insert source vertex into the set and make its distance as 0. WebFeb 3, 2024 · For every vertex being processed, we update distances of its adjacent using distance of current vertex. Following figure is taken from this source. It shows step by step process of finding shortest paths. Following is complete algorithm for finding shortest distances. Initialize dist [] = {INF, INF, ….} and dist [s] = 0 where s is the source ...

WebDijkstra Algorithm is a graph algorithm for finding the shortest path from a source node to all other nodes in a graph (single source shortest path). It is a type of greedy algorithm. It only works on weighted graphs with positive weights. It has a time complexity of O (V^2) O(V 2) using the adjacency matrix representation of graph.
