关联规则程序2 This implementation generates association rules, based on the Apriori algorithm (cfr. Agrawal et al.,1995). It takes as input a file of frequent sets in the format such as generated by the previous implementations.

单处理机的进程调度1、采用时间片轮转调度算法实现进程调度。 2、确定进程控制块的内容，进程控制块的组织方式。 3、完成进程创建原语和进程调度原语。 4、编写主函数对所做工作进行测试。 (The process of scheduling a single processor, using round-robin scheduling algorithm process scheduling. 2, the process control block to determine the content, process control block of the organization. 3, the complete process of creating the original language and process scheduling primitives. 4, the preparation of the work done by the main function of the test.)

Socket,CAsyncSocket,CSocket介绍 Socket有同步阻塞方式和异步非阻塞方式两种使用，事实上同步和异步在我们编程的生涯中可能遇到了很多，而Socket也没什么特别。虽然同步好用，不费劲，但不能满足一些应用场合，其效率也很低。 也许初涉编程的人不能理解"同步(或阻塞)"和"异步(或非阻塞)"，其实简单两句话就能讲清楚，同步和异步往往都是针对一个函数来说的，"同步"就是函数直到其要执行的功能全部完成时才返回，而"异步"则是，函数仅仅做一些简单的工作，然后马上返回，而它所要实现的功能留给别的线程或者函数去完成。例如，SendMessage就是"同步"函数，它不但发送消息到消息队列，还需要等待消息被执行完才返回；相反PostMessage就是个异步函数，它只管发送一个消息，而不管这个消息是否被处理，就马上返回。(SocketCAsyncSocketCSocket)
