Dijkstra's algorithm c++

WebApr 25, 2024 · I'm required to implement the Dijkstra's algorithm via ADT graph using … 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.
