Repeated nearest neighbor algorithm
Add a comment. 1. If you store the graph in an Adjacency Matrix A you can find all length 2 paths by multiplying the matrix with itself ( A^2 ), if this is what you are asking. This will take O (n^3) time to preprocess, but then you can perform lookups for neighbors and "next-neighbors" in constant time.

In the theory of cluster analysis, the nearest-neighbor chain algorithm is an algorithm that can speed up several methods for agglomerative hierarchical clustering. These are methods that take a collection of points as input, and create a hierarchy of clusters of points by repeatedly merging pairs of smaller clusters to form larger clusters.The value of k is very crucial in the KNN algorithm to define the number of neighbors in the algorithm. The value of k in the k-nearest neighbors (k-NN) algorithm should be chosen based on the input data. If the input data has more outliers or noise, a higher value of k would be better. It is recommended to choose an odd value for k to avoid ...I'm trying to develop 2 different algorithms for Travelling Salesman Algorithm (TSP) which are Nearest Neighbor and Greedy. I can't figure out the differences between them while thinking about cities. I think they will follow the same way because shortest path between two cities is greedy and the nearest at the same time. which part am i wrong?
