Algorithmic detection of hypercircles
In the algebraically optimal reparametrization problem, one of the possible approaches deals with computing a parametric variety of Weyl and checking whether this variety is a hypercircle. Here, algorithms to detect whether a curve given parametrically is a hypercircle are provided. (C) 2010 IMACS. Published by Elsevier B.V. All rights reserved.
