For any edge e, the label of e is the positive difference between the two vertices incident with e. In other words, if e is incident with vertices labeled i and j, e will be labeled i − j . Thus, a graph G = (V, E) is graceful if and only if there exists a…

WebGraceful labeling of digraphs One can obtain a graceful labeling for directed graphs having no loops and no parallel arcs analogous to that of graphs by defining an arc value as the simple difference of the values on its end vertices, and by requiring that arc labels be limited in value to the range of the vertex labels by using modular arithmetic.
