The Lloyd algorithm is one of the most popular clustering heuristics for the k-Means Clustering Problem. It first chooses k arbitrary points Centers from Data as centers and then iteratively performs the following two steps:
We say that the Lloyd algorithm has converged if the centers (and therefore their clusters) stop changing between iterations.
Given: Integers k and m followed by a set of points Data in m-dimensional space.
Return: A set Centers consisting of k points (centers) resulting from applying the Lloyd algorithm to Data and Centers, where the first k points from Data are selected as the first k centers.
