The virtual memory pages whose page frames are to be reassigned are selected using the VMM's page replacement algorithm.
可以使用VMM的页面置换算法来选择要重新分配页帧的虚拟内存页面。
VMM is constantly lurking and working in the background trying to steal frames that have not been recently referenced, using the page replacement algorithm discussed earlier.
VMM一直在后台运行，尝试使用前面介绍的页面置换算法偷取最近没有引用过的页帧。
But in some cases, LRU algorithm causes many page faults, so improving LRU page replacement algorithm can reduce page faults, and therefore improve the performance of the system.
但LRU算法在某些情况下会产生较多的缺页失败，改进LRU算法，降低缺页失败次数，可以有效地提高系统性能。
Because the page replacement algorithm is always looking for free frames while it is doing its scanning on systems with a lot of memory, the number of frames to scan can be significant.
在对有大量内存的系统进行扫描时，因为页面置换算法始终寻找空闲帧，所以需要扫描的页帧数量非常大。
The process by which a page is selected to swap to storage is called a page-replacement algorithm and can be implemented using a number of algorithms (such as least recently used).
选择一个页面来交换存储的过程被称为一个页面置换算法，可以通过使用许多算法(至少是最近使用的)来实现。
The VMM has a page-replacement algorithm, which assigns the page frames and determines exactly which virtual-memory pages currently in RAM will have their page frames brought back to the free list.
VMM 提供了一种页面置换算法，该算法用于分配页帧，以及确定应该将当前RAM 中的哪些虚拟内存页面的页帧置换回空闲列表。
