Graceful Graphs and Graceful Labelings: Two Mathematical Programming Formulations and Some Other New Results

open access: yes, 2003
Given a graph G consisting of vertices and edges, a vertex labeling of G is an assignment f of labels to the vertices of Gthat produces for each edge xy a label depending on the vertex labels f(x) and f(y).
