分布式的Top-k查询算法.通信量最少，并编实现并测试该算法。-Distributed Top-k query algorithms. The least traffic, and prepared to achieve and test the algorithm.

kmeans算法，　K-means算法是最为经典的基于划分的聚类方法，是十大经典数据挖掘算法之一。K-means算法的基本思想是：以空间中k个点为中心进行聚类，对最靠近他们的对象归类。通过迭代的方法，逐次更新各聚类中心的值，直至得到最好的聚类结果-kmeans algorithm, K-means algorithm is the most classic divide-based clustering method is one of the top ten classical data mi

网络中的前k子图匹配查询算法的实现，复杂网络分析中的重要内容。-The implementation of top-k interesting subgraph matching algorithm in network, which is an important content in network analysis.
