Abstract :
Recently, Snyder and Tang [1] proposed an algorithm for finding the diameter of a convex polygon. In this note a family of convex polygons is described for which their algorithm fails. It is also pointed out that the diameter of an arbitrary simple n-vertex polygon can be computed in O(n) time.
