... a little bit of new machinery. An often studied subset of graceful labellings are bipartite graceful (or α -graceful) labellings; the labelling f of G is bipartite if the vertices of G have a bipartition ... variations of gracefulness which relax distinctness conditions (such as equitable labellings) introduce new constraints as well. While in a sense vertex-relaxed gracefu...
