Let . be a vector of vertex ., and let . be a vector of . at the vertices. Then . . . on . if the constraints . are satisfied for all ., where .(.) denotes the neighborhood of .. Given a req

,Das Kapital in der Wirtschaft Robinson’s, that no two adjacent vertices are incident to the same sum of labels. In connection with recent optimisation variants of this conjecture, we study the role of label 3 in proper 3-labellings of graphs. Previous studies suggest that, in general, it should always be possible to produce proper 3-labell

In 2007, Derhy and Picouleau considered the natura
