Note on the relation between radius and diameter of a graph

Ferdinand Gliviak, Peter Kyš (1995)

Mathematica Bohemica

The known relation between the standard radius and diameter holds for graphs, but not for digraphs. We show that no upper estimation is possible for digraphs. We also give some remarks on distances, which are either metric or non-metric.
