A comment on Executing gradient descent on the earth. Parent comment
If you consider only the "orange peel", if the center is 0 and r=1, then the 1D version is just two points {-1} and {1}, not only one point.
If you consider only the "whole orange" then the 1D case is the segment [-1, 1], if the center is 0 and r=1
In both case it is equal to the 1D "square" equivalent.
