Shortest Path using Dijkstra

WebDijkstra’s Algorithm Input − A graph representing the network; and a source node, s Output − A shortest path tree, spt[], with s as the root node. Initializations − An array of distances dist[] of size V (number of nodes), where dist[s] = 0 and (infinite), where u represents a node in the graph except s. WebThis algorithm is also efficient, meaning that it can be implemented in a reasonable amount of time. Dijkstra’s algorithm takes around V2 calculations, where V is the number of vertices in a graph. A graph with 100 vertices would take around 10,000 calculations. While that would be a lot to do by hand, it is not a lot for computer to handle. doddridge county wv farms for saleWebThe Dijkstra Source-Target algorithm computes the shortest path between a source and a target node.
