WebThat seems the natural way to introduce Dijkstra's algorithm. We can say that we will construct S v 's that reach the respective objectives one edge at a time, selecting the "best" "available" element at every step, i.e., selecting the "unsettled" node that is "nearest" to the source at every step. So, the algorithm is greedy.
