Shortest path problem

(6, 4, 5, 1) and (6, 4, 3, 2, 1) are both paths between vertices 6 and 1

Shortest path (A, C, E, D, F) between vertices A and F in the weighted directed graph

In graph theory, the shortest path problem is the problem of finding a path between two vertices (or nodes) in a graph such that the sum of the weights of its constituent edges is minimized.

The problem of finding the shortest path between two intersections on a road map (the graph's vertices correspond to intersections and the edges correspond to road segments, each weighted by the length of its road segment) may be modeled by a special case of the shortest path problem in graphs.
