Set two points in the plane space. Their coordinates are $ (x1, y1) $, $ (x2, y2) $
$ Dis = | x1-x2 | + | y1-y2 | $
That is, the sum of the two-point horizontal and vertica

Find a point from N points to minimize the sum of the distance from the other point to this point.Ideas:It can be found that the distance between the two points is |x1-x2| + |y1-y2|, which is the distance between two points of Manhattan.The naïve approach is to traverse all points and enumerate the sum of the distance between the point and the other points, b

First, let's take a look at Manhattan,Manhattan is an extremely prosperous BlockThere are many tall buildings and streets. There is no straight path from location a to location B. There must be a detour, and at least it must pass through Location C and take location AC and CB to arrive. Because the streets are quite regular, ACB is like a right angle 3 angular, AB is the oblique side, AC and CB are the stra

There is a rectangular area containing nxm cells. Both cells is marked with "2", and another, and "3". Some cells is occupied by obstacles. You should connect the both "2" s and also the "3" s with non-intersecting lines. Lines can run only vertically or horizontally connecting centers of cells without obstacles.
Lines cannot run on a cell with an ob
