Lm distance


Definition: The generalized distance between two points. In a plane with point p1 at (x1, y1) and p2 at (x2, y2), it is (|x1 - x2|m + |y1 - y2|m)1/m.

Also known as Minkowski distance.

See also Euclidean distance, rectilinear, Manhattan distance, Hamming distance.

Note: This is easily generalized to higher dimensions. Euclidean distance is L2 distance. Rectilinear, Manhattan or Hamming distance is L1 distance. L distance is max(|x1 - x2|, |y1 - y2|). Adapted from [CLR90, page 912].
