Abstract
In this paper, k-means algorithm is presented. It is a heuristic algorithm for solving NP-hard optimisation problem of classifying a given data into clusters, with a number of clusters fixed apriori. The algorithm is simple and it's convergence is fast, what makes it widely used, despite its tendency of stoping in a local minimum and inability of recognizing clusters not separated by hyper-planes. The method of the first variation as a tool for escaping from a local minimum is also presented in the paper.
