(classic problem)
Definition: Find the weight (or length) of the shortest paths between all pairs of vertices in a weighted, directed graph.
See also Floyd-Warshall algorithm, Johnson's algorithm similar problems: single-source shortest-path problem, shortest path, minimum spanning tree, traveling salesman, all simple paths.
Note: The problem is to find the weights of the shortest paths between all pairs of vertices. For a map, it is to produce the (shortest) road distances between all cities, not which roads to take to get from one city to another.
