The reason why Dijsktra's algorithm works the way it does is in part because it exploits the fact that the shortest path between node u and w that includes point v also contains the shortest path from u to v and from v to w. If there existed something shorter between u to v, then it wouldn't be the shortest path. skyelectric.com
