In the same decade, Prim and Kruskal achieved optimization strategies that were based on minimizing path costs along weighed routes. However, the length of a path between the root and any other node in the MST might not be the shortest path between those two nodes in the original graph. It is easier to programme on a computer. As one travels along the path, one must encounter at least one edge f joining a vertex in set P to one that is not in set P. Now, at the iteration when edge e was added to tree T, edge f could also have been added and it would be added instead of edge e if its weight was less than e, and since edge f was not added, we conclude that.
