The Dijkstra algorithm is an algorithm used to solve the shortest path problem in a graph. This means that given a number of nodes and the edges between them as well as the “length” of the edges (referred to as “weight”), the Dijkstra algorithm is finds the shortest path from the specified start node to all other ... WebApr 6, 2024 · What is Dijkstra Algorithm Dijkstra algorithm is a generalization of BFS algorithm to find the shortest paths between nodes in a graph. For a given graph G = (V, E) and a distinguished vertex s, then we can find the shortest path from s to every other vertex in G with the help of Dijkstra algorithm. ruth smith and valentine hewlett peters
