本程序实现了操作系统中页式虚拟存储管理中缺页中断理想型淘汰算法，该算法在访问串中将来再也不出现的或是在离当前最远的位置上出现的页淘汰掉。这样，淘汰掉该页将不会造成因需要访问该页又立即把它调入的现象。该程序能按要求随机确定内存大小，随机产生页面数，进程数，每个进程的页数，给进程分配的页数等，然后运用理想型淘汰算法对每个进程进行计算缺页数，缺页率，被淘汰的序列等功能。-This procedure has the operating system virtual memory management page in the page fault ideal type out algorithm in the access string does not occur again in the future or furthest away from the current position on the page eliminate. In this way, eliminate the page will not be caused by the need to visit the page immediately transferred to the phenomenon of it. The program randomly determined according to the requirements of memory size, page number of randomly generated, the process of the number of pages for each process to the process of distribution of the number of pages, etc., and then out of the use of ideal-type algorithm for each process to calculate the number of pages missing, missing page rate, be eliminated sequence functions.
