WebThe nearest-neighbor chain algorithm constructs a clustering in time proportional to the square of the number of points to be clustered. This is also proportional to the size of its input, when the input is provided in the form of an explicit distance matrix. The algorithm uses an amount of memory proportional to the number of points, when it ... Webusing the nearest neighbor method is 2 + 1 + 9 + 9 + 21 = 42. 4.2 Greedy Greedy algorithm is the simplest improvement algorithm. It starts with the departure Node 1. Then the algorithm calculates all the distances to other n−1 nodes. Go to the next closest node. Take the current node as
