Apr 7, 2018 · You are comparing latitude and longitude when instead you need to compare latitude with latitude and longitude with longitude. The Manhattan distance between (1,3) and (2,4) is |1-2|+|3-4|, not |1-4|+|2-3|. It should also be pointed out that since you're taking the min and max of the same range, you don't actually need the absolute value function.
Dec 10, 2017 · I want to implement somthing similar but using Manhattan distance instead. So far I've got close but fell short trying to rearrange the absolute differences. As I understand it, the Manhattan distance is. I tried to solve this by considering if the absolute function didn't apply at all giving me this equivalence
Oct 3, 2015 · In the webpage it uses a = sin²(Δφ/2) + cos φ1 ⋅ cos φ2 ⋅ sin²(Δλ/2), but that would give us a straight-line distance. So to do it with Manhattan distance, we will do the latitude and longitude distances separately. First, we get the latitude distance, as if longitude was 0 (that's why a big part of the formula got omitted):
Manhattan distance is the taxi distance in road similar to those in Manhattan. You are right with your formula . distance += abs(x_value - x_goal) + abs(y_value - y_goal) where x_value, y_value is where you are and x_goal, y_goal is where you want to go.
Apr 10, 2015 · For a square grid the euclidean distance between tile A and B is: distance = sqrt(sqr(x1-x2)) + sqr(y1-y2)) For an actor constrained to move along a square grid, the Manhattan Distance is a better measure of actual distance we must travel: manhattanDistance = abs(x1-x2) + abs(y1-y2))
May 1, 2020 · I'm implementing NxN puzzels in Java 2D array int[][] state. am required to use the Manhattan heuristic in the following way: the sum of the vertical and horizontal distances from the current node to the goal node/tile +(plus) the number of moves to reach the goal node from the initial position
Sep 29, 2016 · The Manhattan is defined as abs(x_value - x_goal) + abs(y-value - y_goal) where x_goal and y_goal are x and y value of the given element in the goal state. – GenericUser01 Commented Sep 29, 2016 at 1:40

I want to compute the "MANHATTAN DISTANCE" also called "CITY BLOCK DISTANCE" among pairs of coordinates with LAT, LNG. Following this post Manhattan Distance for two geolocations I had computed the distance using the haversine formula:
