WebThis is a Java Program to perform Dijkstra’s Shortest path algorithm. For a given source vertex (node) in the graph, the algorithm finds the path with lowest cost (i.e. the shortest path) between that vertex and every other vertex. It can also be used for finding costs of shortest paths from a single vertex to a single destination vertex by ... phone blank screenWebOct 8, 2012 · In shortest-path algorithms, a high cost tells the algorithm "do not go down that path". So by default, we only know that the starting node is apart of the shortest path, while all other nodes are still undetermined. Therefore, we assign a low cost of zero to the starting node (e.g. S), and a high cost of infinity to every other node (e.g. A, E). how do you know eggs are fertilized
