Try to calculate the Supremum distance for the following data points: x1:(2,5,1,0) and x2: (1,3,4,-1) Whenever a supremum exists, its value is unique. First observe, the manhattan formula can be decomposed into two independent sums, one for the difference between x coordinates and the second between y coordinates. In 2D, given 2 points (x1, y1) and (x2, y2), the Euclidean distance between them is defined as sqrt((x2-x1)^2 + (y2-y1)^2). Although p can be any real value, it is typically set to a value between 1 and 2. It's very late and this is one of those stupid problems that I don't actually need to solve, but it'll drive me mad until I learn the answer.
