WebDijkstra's algorithm is an algorithm for finding the shortest paths between nodes in a graph. Dijkstra's algorithm is applicable for: Both directed and undirected graphs. All edges must have nonnegative weights. Graph must be connected. Dijkstra's algorithm was, originally, published by Edsger Wybe Dijkstra, winner of the 1972 A. M. Turing Award. WebHow Dijkstra's Algorithm works. Dijkstra's Algorithm works on the basis that any subpath B -> D of the shortest path A -> D between vertices A and D is also the shortest path between vertices B and D. Each subpath is …
