The Locale object defines the origin, in high-resolution coordinates, of its attached branch graphs. In a directed graph, edges are one-way: an edge e = 〈A,B〉 indicates B that is directly reachable from A. Gridlines: NORMAL LESS OFF. The emphasis in this article is the shortest path problem (SPP), being one of the fundamental theoretic problems known in graph theory, and how the Dijkstra algorithm can be used to solve it.
