WebGiven a weighted, undirected and connected graph of V vertices and an adjacency list adj where adj[i] is a list of lists containing two integers where the first integer of each list j denotes there is edge between i and … WebDijkstra’s Algorithm. The algorithm we are going to use to determine the shortest path is called “Dijkstra’s algorithm.”. Dijkstra’s algorithm is an iterative algorithm that provides us with the shortest path from one particular starting node to all other nodes in the graph. Again this is similar to the results of a breadth first search.
