聚类-k均值算法
K-means算法是基于划分的思想，因此算法易于理解且实现方法简单易行，但需要人工选择初始的聚类数目即算法是带参数的。类的数目确定往往非常复杂和具有不确定性，因此需要专业的知识和行业经验才能较好的确定。而且因为初始聚类中心的选择是随机的，因此会造成部分初始聚类中心相似或者处于数据边缘，造成算法的迭代次数明显增加，甚至会因为个别数据而造成聚类失败的现象。(K-means algorithm is based on the idea of partitioning, so the algorithm is easy to understand and the implementation method is simple and feasible, but it requires manual selection of the initial number of clusters, that is, the algorithm is with parameters. The number of classes is often very complex and uncertain, so professional knowledge and industry experience are needed to better determine. Moreover, because the selection of initial clustering centers is random, some initial clustering centers will be similar or at the edge of data, resulting in a significant increase in the number of iterations of the algorithm, and even the phenomenon of clustering failure due to individual data.)

内部排序算法比较
一、需求分析
1． 实验要对以下6种常用的内部排序算法进行实测比较：起泡，直接插入，简单选择，快速，希尔，堆排序。
2． 待排序表的表长不小于100，其中的数据要用伪随机数产生（RAND（）），至少要用5组不现的输入数据作比较，比较的指标为有关键字参加的比较次数和关键字参加的比较次数和关键字的移动次数。
3． 最后要对结果作出简单分析，包括对各组数据得出结果波动大小的解释。
-internal sorting algorithm 1, a demand analysis. Experiment on the following six kinds of internal sorting algorithm measured comparison : foaming, direct insertion, simple choice, rapid, Hill, Heap Sort. 2. Sorting tables to the long table is not less than 100, which use the data generated pseudo-random number (RAND ()), be at least five sets of input data are provided for comparison. comparable indicators for the keyword in the number of keywords and the number of participants and the number of mobile keyword. 3. Finally, the results of a simple analysis, including data on the outcome of fluctuations in the size of explanation.
