最常见的算法使用迭代优化技术。由于它的普遍性,它通常被称为“ k-means算法”,也被称为[[劳埃德算法 Lloyd's algorithm]],特别是在计算机科学界。有时也称为“朴素k-means”,因为存在更快的替代方法。<ref>{{Cite journal|last=Pelleg|first=Dan|last2=Moore|first2=Andrew|date=1999|title=Accelerating exact k -means algorithms with geometric reasoning|url=http://portal.acm.org/citation.cfm?doid=312129.312248|journal=Proceedings of the Fifth ACM SIGKDD International Conference on Knowledge Discovery and Data Mining - KDD '99|language=en|location=San Diego, California, United States|publisher=ACM Press|pages=277–281|doi=10.1145/312129.312248|isbn=9781581131437}}</ref>
