Description: 处理机调度，编写一个进程调度程序，允许多个进程共行的进程调度程序。
进程调度算法：采用最高优先数优先的调度算法（即把处理机分配给优先数最高的进程）和先来先服务算法。
每个进程有一个进程控制块（PCB）表示。进程控制块可以包含如下信息：进程名、优先数、到达时间、需要运行时间、已用CPU时间、进程状态等等。
进程的优先数及需要的运行时间可以事先人为地指定（也可以由随机数产生）。进程的到达时间为输入进程的时间。
进程的运行时间以时间片为单位进行计算。
每个进程的状态可以是就绪 W（Wait）、运行R（Run）、或完成F（Finish）三种状态之一。
就绪进程获得 CPU后都只能运行一个时间片。用已占用CPU时间加1来表示。
如果运行一个时间片后，进程的已占用 CPU时间已达到所需要的运行时间，则撤消该进程，如果运行一个时间片后进程的已占用CPU时间还未达所需要的运行时间，也就是进程还需要继续运行，此时应将进程的优先数减1（即降低一级），然后把它插入就绪队列等待CPU。
每进行一次调度程序都打印一次运行进程、就绪队列、以及各个进程的 PCB，以便进行检查。
重复以上过程，直到所要进程都完成为止

Process scheduling algorithm : Highest priority for priority scheduling algorithm (namely processors allocated to the highest priority in the process) and a first-come first-service algorithm .

Process control block may contain the following information : process, and a number of priority, arriving in time, the running time, CPU has spent time, the process of the state and so on. Several priorities for the process of the operation and needs time to be designated prior to artificially (and also by the random number generator).

Description: 题目：设计一个请求页式存储管理方案，并编写模拟程序实现
具体要求：
1、产生一个需要访问的指令地址流，为不失一般性，可以适当地（用人工指定地方法或用随机数产生器）生成这个序列，使得 50％的指令是顺序执行的。25％的指令均匀地散布在前地址部分，25％的地址是均匀地散布在后地址部分
2、 页面淘汰算法采用 FIFO页面淘汰算法，并且在淘汰一页时，只将该页在页表中抹去。而不再判断它是否被改写过，也不将它写回到辅存
3、产生一个需要访问的指令地址流；指定合适的页面尺寸（例如以1K或2K为1页；指定内存页表的最大长度，并对页表进行初始化
4、每访问一个地址时，首先要计算该地址所在的页的页号，然后查页表，判断该页是否在主存。如果该页已在主存，则打印页表情况；如果该页不在主存且页表未满，则调入一页并打印页表情况；如果该页不在主存且页表已满，则按 FIFO页面淘汰算法淘汰一页后调入所需的页，打印页表情况 。逐个地址访问，直到所有地址访问完毕

Description: 使用到的参数跟谈到弹性网络的那一章里头所讲的是一样的， ke 则是终止条件。如果 step 被打勾，则程式在每一步之间会暂停 100毫秒（或其他使用者输入的数值）。如果 Random 被打勾，则程式会以系统时间作为乱数产生器的种子数，否则，就以使用者输入的数（ Random 右边那一格）为种子数。
你可以利用 load 来载入推销员问题档与其最佳解，如此便可比较弹性网络所找出来的解与最佳解差了多少。
Central, Radius, and Error 这三个参数的前两个，只影响弹性网络的起使位置和大小，对求解没有影响。第三个参数代表城市与网络点之间的容忍距离，也就是说，如果某城市与某网络点之间的距离，小于容忍距离，那就把这个城市当成是被该网络点所拜访。
按下小 w按钮会将目前的结果与参数值写到“en.out”这个档案。使得我们可以很方便地来比较不同参数的效果。

You can use load to stall contained salesman problem with the optimal solution, so can be more flexible network to find the best solution and the deficit with a number of questions.

Description: 今天有点郁闷，不想干活。整理代码的时候，看到了这个好久之前写的代码，于是想整理出来供大家拍砖。XML的解析对于.Net平台那真是太简单不过了，感谢微软。但对于C++语言的XML解析就没那么容易了。有一个开源的XML4C是IBM的,功能强大，但代码大的有几M,而且对于GB2312的支持有问题，据说能解决，但可能是我天生愚钝，当初我花了2周时间也没搞定，最后放弃，自己写了一个。咦？还能跑起来，也能跨平台:)。 写这个XML解析类，以功能最简单，最实用，最常用的功能为原则，因为只能解析，查找，没有XML文档生成器。如果需要生成XMl文档，还是自己拼凑字串吧。
