public class ManhattanDistance extends NormalizableDistance implements TechnicalInformationHandler
Implements the Manhattan distance (or Taxicab geometry). The distance between two points is the sum of the (absolute) differences of their coordinates.

For more information, see:

Valid options are:

 -D
  Turns off the normalization of attribute 
  values in distance calculation.
 -R <col1,col2-col4,...>
  Specifies list of columns to used in the calculation of the 
  distance. 'first' and 'last' are valid indices.
  (default: first-last)
 -V
  Invert matching sense of column indices.
