We show that this measure is related to the average winding number of its Gauss map. Using this relationship, we give an algorithm for computing the writhing number for a polygonal knot with n edges in time roughly proportional to n(1.6). We also implement a different, simple algorithm and provide experimental evidence for its practical efficiency. SIAM2002San Francisco, CA, USA eng 9780898715132 791 - 799 yes P. Agarwal, H.
