给定一个（无向）图G，及G中的两点s、t，确定一条从s到t的最短路径。-Given a (undirected) graph G, and G in two points s, t, determined from s to t of a shortest path.

自动抄表计费系统、 基于 GSM。其我的项目。bt 不幸的是我可以没有准备好到AT89S52 微控制器方案......，所以请能 at89s52 microcontrollr 编程数据......plz 帮我

dijkstra算法，用于寻找已建立图的最短路径，是非常有用的一个算法-Dijkstra algorithm, has been established for finding the shortest path map is a very useful algorithm

这是一个生成全排列的程序,采用最小变化算法,相邻两个序列之间只有两个数的次序不同,每交换两个数,便形成一个新的序列,速度非常快.-This is a whole generation with a procedure using the smallest change algorithm sequence between two adjacent only two of several different order every two exchanged a few, it will lead to a new series, very fast.

ACM解题报告，必有有用，特别对于初学者，看是否对你有帮助-ACM problem-solving report, there must be useful, especially for beginners to see if there is help for you

address management vb6

This program demonstrates how to do disconnected briefcase applications with ADO. When the Connected checkbox is unchecked the application is switched into offline mode. If the application is exited at that point then the data is persisted to a file on disk (along with any edits to the data). When the application is restarted it will load the persisted data if present, otherwise it will fetch the data from the database.

数据结构算法演示-demonstration algorithm data structure

操作系统中的文件是通过文件目录项来管理的，为了管理和查找的方便，按层次把文件目录项组织起来，同一层上的目录构成该层上的目录，第一层为根目录，一下为各层子目录。 假设以一串字符代表一个文件，每个字符表示一个记录。 在建立上述目录结构的基础上，建立相应的管理系统并要求完成以下各项操作： 1． 一次建立各个文件 2． 查访两个用户的所有文件 3． 查访用户sun 是否有文件AB 4． 删除用户sun的文件AC,然后在分别查访两个用户的全部文件，检查是否已经删除文件AC 5． 撤销用户sun,并检查是否被删除 6． 删除用户sun的全部文件，然后在撤销sun用户，在查访用户sun, 检查其是否已被撤销。 在建立一个新用户及新用户的两个文件，然后查该两个用户的所有文件-operating system, the paper is to document catalog items to the management, in order to manage and facilitate the search, according to the document level directory entries organizations, the same floor on which constitute the directory contents on the floor, the first layer of the root directory to look for levels of subdirectories. Assuming that the representative of a string of characters, each character expressed a record. In establishing the directory structure on the basis of the establishment of a corresponding system of management and asked to accomplish the following : 1. Once established two separate files. Visits to the two users of all three docum
