! HDU 4311 minimum Manhattan distance-Thinking timing-(separated and sorted by horizontal and vertical coordinates), hdu Manhattan Question: There are n points. Start from a point in the n points and find the distance and minimum value of the Manhattan point. Analysis: Brute-force enumeration times out again. This type of question is generally considered, and mo

Distance between Manhattan and cherbihov and their mutual transformation; distance between Manhattan and Xuefu This article only discusses the distance between the two-dimensional space and the chibbihov.Manhattan distance Definition 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

HDU 4311Test instructions: There are n points on the plane, one point (x, y) can only reach (X-1,y), (X+1,y), (×, y-1), (x, y+1) 4 points. 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

It's just a second answer, and then consider how to validate.Meet the Bi−ai≤mid b_i-a_i \le mid point on the tube, set the transmission point built in X,y X,y, the remaining points need to meet:| x−ai|+| Y−bi|≤mid | x-a_i|+| Y-b_i|\le midThis is difficult to do if we find that we consider enumerating an endpoint. Can be transformed, note that the constraint above is a form of a Manhattan distance, that is to say (X,y) (X,y), (Ai,aj) (A_i,a_j) as a poi

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

Test instructions: There are n points, which is the starting point for a point in this N-point, and the distance and minimum of Manhattan to the pointsAnalysis:Violent enumeration and time-outs, the problem is generally test thinking, mostly with the skills to find an efficient method. Personally think this question is a type of topic with the previous article. This thought should be remembered. This question is also used "divide the rule", although t

 Test instructions: n points on the surface, a point to the other points of the Manhattan distance minimum and, Chebyshev distance minimum and.Idea: for Chebyshev distance can be converted to Hamiltonian distance, the method is to rotate the coordinates of each point counterclockwise 45 degrees and then enlarge sqrt (2) times, replaced by coordinate means (x, y) and (x-y,x+y).For the first question, the Manhatta
