## Optimal Orientations of Annular Networks

### Authors: Jean-Claude Bermond, Johny Bond, Carole Martin, Aleksandar Pekec and Fred S. Roberts

ABSTRACT

Annular Network $AN(c,s)$ is a graph representing a $c\times s$ grid in polar coordinates. We give lower bounds for the diameter of orientations of $AN(c,s)$ and provide orientations which show that bounds are tight in most cases.
