Arankings of Trees
For a graph G = (V, E), a function f : V (G) → {1, 2, . . ., k} is a kranking for G if f(u) = f(v) implies that every u − v path contains a vertex w such that f(w) > f(u). A minimal k-ranking, f, of a graph, G, is a k-ranking with the property that decreasing the label of any vertex results in th...
