在 Visual Basic 6.0 开发项目。它是一个快递管理系统来管理和跟踪快递。欢迎大家下载、试用。谢谢大家的支持！

一 开发环境 OS: Windows 2000 Server + SP2 IDE: Visual Studio 6.0 + SP5 DataBase: SQL 2000 Server + SP2 二 运行 1：创建数据库 将Hotel.sql中的SQL语句考入SQL Server的查询分析器中，全部运行； 2：建立ODBC数据源 数据原名称为Hotel_MIS-a development environment OS : Windows 2000 Server SP2 IDE : Visual Studio 6.0 SP5 DataBase : SQL Server 2000 running a two SP2 : Hotel.sql database will be created in the SQL Server SQL admitted to the inquiry Analyzer All operations; 2 : build ODBC data source data formerly known as Hotel_MIS

清华大学数据结构课上实现的B+树，设计一个4阶B+树，包括： (1) 叶子的每个记录应该包括4字节（long）关键码值和60字节的数据字段(存储文件名等，可以自定)，设每个叶子可以存储5条记录，而内部节点应该是关键码值/指针对。此外，每个节点还应该有指向同层下一个节点的指针、本节点存储的关键码数等； (2) 此4阶B+树应该支持插入、删除以及根据给定关键码值进行精确检索与关键码范围检索； (3) 显示（打印）此4阶B+树的生长(含删除节点)过程实例；-Tsinghua University class data structure to achieve the B-tree, the design of a B-tree four bands, including : (a) the leaves of each record should include 4-byte (long) key code value and 60 gigabytes of data fields (document storage, etc., can be set), set up each leaf store five records, and internal nodes is the key code value/means against. In addition, each node should have the same point under a layer of the target node, the node storage key code number; (2) The B-tree four bands should support the insertion, deletion and with the given key code value accurate retrieval and key codes scope retrieval; (3) Display (Print ) This four bands B-tree growth (including the deletion of nodes) process examples;

图的常用算法，比较全面 并有一种求图的最短路径的算法， 欢迎指正，-map commonly used algorithms, a more comprehensive and a map for the shortest path algorithm welcome correction, thank you

在一个圆形操场的四周摆放着n堆石子。现要将石子有次序地合并成一堆。规定每次只能选相邻的两堆石子合并成新的一堆，并将新的一堆石子数记为该次合并的得分。试设计一个算法，计算出将n堆石子合并成一堆的最小得分和最大得分，并分析算法的计算复杂度。-in a circle around the playground are placed n gravel pile. Is a stone should order to be merged into a heap. Stipulated that only elected adjacent to the pile of gravel into the new heap, and a new pile of gravel credited for the combined scores. Design a test algorithm to calculate n heap into a pile of gravel to the minimum score and the biggest score and analysis of algorithm complexity.

神经网络中的K均值聚类算法II： 1.KMIn为输入数据文本，其中，第一个参数为所要聚类点个数，第二个参数为聚类点的维数,第三个参数为所要求聚类的个数 2.KM2OUT为经过K均值聚类算法II计算后得到的结果-Neural network in K-means clustering algorithm II: 1.KMIn input data for the text, of which the first parameter to be the number of clustering points, the second parameter is the dimension of clustering points, the third parameter for the clustering the number of requests for 2.KM2OUT after K-means clustering algorithm II calculation results

题目：设计一个题目，演示用算符优先法对算术表达式求值的过程。 概要设计 1、顺序扫描中缀算术表达式，当读到数字时直接将其送至输出队列中； 2、当读到运算符时，将栈中所有优先级高于或等于该运算符弹出，送至输出队列中，再将当前运算符入栈； 3、当读入左括号时，即入栈； 4、当读到右括号时，将靠近栈顶的第一个左括号上面的运算符全部一次弹出，送至输出队列中，再删除栈中的左括号。 5、使用VS栈来存储读入的操作和运算结果，然后进行数字字符到数值的转换。 -Title: Design of a topic, presentation operator priority method with arithmetic expression evaluation process. Summary of design 1, the order of scanning arithmetic infix expressions, when they read numbers directly to the output queue 2, when they read operator, it will stack all priority higher than or equal to the operator pop-up , sent to the output queue, and then the current operator入栈 3, when read left brackets, that is, when入栈 4, when they read the right brackets, it will be near the Top-left of the first operator in brackets above All a pop-up, sent to the output queue, and then delete stacks of left brackets. 5, the use of VS stack to store read operation and computing the results of numeric characters and then proceed to the numerical co
