Computing constrained minimum-width annuli of point sets
We study the problem of determining whether a manufactured disk of certain radius r is within tolerance. More precisely, we present algorithms that, given a set of n probe points on the surface of the manufactured object, compute the thinnest annulus whose outer (or inner, or median) radius is r and that contains all the probe points. Our algorithms run in O(nlogn) time.
