用prim算法实验最小生成树 本程序中用到函数adjg( )，此函数作用是通过接受输入的点数和边数，建立无向图。函数prg( )用于计算并输出无向图的邻接矩阵。函数prim( )则用PRIM算法来寻找无向图的最小生成树 定义了两个数组lowcost[max],closest[max]，若顶点k加入U中，则令lowcost[k]=0。 定义二维数组g[ ][ ]来建立无向图的邻接矩阵。 -Prim algorithm using minimum spanning tree of the experimental procedures used in function adjg (), this function is through the acceptance of input points and edges, the establishment of a directed graph. Function of prg () used to calculate and output undirected graph of adjacency matrix. Function prim () is used PRIM Algorithm to find the undirected graph of the minimum spanning tree array defines two lowcost [max], closest [max], if it joined the U of k vertices, then the lowcost [k] = 0. The definition of two-dimensional array g [] [] to create a undirected graph of adjacency matrix.

设有n个人站成一圈，每个人持有一个密码（正整数)。现从第t个人开始，按顺时针方向“1,2,3,4,…”循环报数，数到m1（第t个人所持密码）的人出列，然后从出列者的下一个人重新开始报数，数到m2（刚出列者所持密码）的人又出列，如此重复进行，直到n个人都出列为止。-something like Joseph problem

一种基于数据访问流的数据库索引优化方法该方法通过集成业务流程模型与数据模型，抽取了流程活动中包含的数据访问操作和流程的控制结构形成数据访问流，分析了数据访问流中数据访问操作的频度，为频繁数据访问操作所对应的数据项创建索引，达到改善数据访问性能的目的。实验结果表明，该方法提高了数据查询的速度。-A novel method called data-access-flow based index optimization (DAFIO) is proposed to provide automatic index select for databasein order to improve the data access performance. By integrating the data model and process model of the IT systems and getting data access flow, theDAFIO method can analyze the data access flow to find those data item which are accessed frequently, and then create indexes for these frequentitems. The experiment results show that the novel method is effective to improve the data access performance.
