Distance between points using the Follower algorithm. To verify the distance algorithms, the ‘Follower’ algorithm has been developed. Follower chooses two points and determines the distance between one of them and all of the points on a line between the two original points. Here, one unreduced point is chosen and the second point is the reduced point of that point. So the distance between the original point and the final point is zero. Distances are shown for the metric (Andrews & Bernstein, 2014 ▸), the metric (Andrews et al., 1980 ▸), the metric (Andrews et al., 2019 ▸), and the two implementations in . Timing in ms: (NCDist) 4542, 676, 7, S6Dist 394, CS6Dist 14.
