[OS program] yemian DL : 0: 根据模拟的页式管理设计，掌握在页式存储管理中最基本的三种页面调度算法FIFO、LRU以及OPT。但在三种算法中均要求在调度程序中产生的页面序列是随机产生的，而不是人为的输入，在执行时只需改变页面的大小及内存容量就可以得到不同的页面序列，另外还需要说明随机的性能和其性能可能对算法的影响，并对随机性要有一定的参数控制能力。此外，计算并输出FIFO、LRU以及OPT算法在不同内存容量下的命中率。-According to the simulation page management design, master page storage management in the most basic of the three pages scheduling algorithm FIFO, LRU and OPT. But in three algorithms are required in the scheduler pages generated sequences are randomly generated, rather than artificial inputs, when executed simply by changing the page size and the amount of memory you can get a different page sequence also need described random performance and its performance may be on the algorithm, and to have a certain randomness parameter control capabilities. In addition, calculate and output FIFO, LRU and OPT algorithms under different memory hit rate.
