Graph shortest path online
WebThe ideas explored in graph theory are frequently applied to computing algorithms: the language and instructions of software. Since resources are limited (time, computing power), mathematicians and computer scientists seek the most efficient ways to compute. Graph theory helps them find the shortest path from A to B. Web2 Answers. Although simple to implement, Dijkstra's shortest-path algorithm is not optimal. A guaranteed linear time, linear space (in the number of edges) algorithm is referenced by the Wikipedia article Shortest path problem as: Thorup, Mikkel (1999) "Undirected single-source shortest paths with positive integer weights in linear time".
