You are calculating the distances from a beginning vertex, say S, to all the other vertices. At some point, you have intermediate results -- current estimates.

A graph is a structure that comprises a set of vertices and a set of edges. So in order to have a graph we need to define the elements of two sets: vertices and edges. The vertices are the elementary units that a graph must have, in order for it to exist.

In his 1736 paper on the Seven Bridges of Königsberg, widely considered to be the birth of graph theory, Leonhard Euler proved that, for a finite undirected graph to have a closed walk that visits each edge exactly once (making it a closed trail), it is necessary and sufficient that it be connected except for isolated vertices (that is, all edges are contained in one component) and have even degree at each vertex. The corresponding characterization for the existence of a closed walk vis… http://www-math.ucdenver.edu/~wcherowi/courses/m4408/gtln4.html
