Let C be a polygonal cycle on n vertices in the plane. A randomizedalgorithm is presented which computes in O(n log3 n) expectedtime, the edge of C whose removal results in a polygonal path of smallestpossible dilation. It is also shown that the edge whose removal gives apolygonal path of largest possible dilation can be computed in O(n log n)time. If C is a convex polygon, the running time for the latter problembecomes O(n). Finally, it is shown that for each edge e of C, a (1 - Ɛ)-approximation to the dilation of the path C \ {e} can be computed inO(n log n) total time.
