摘要：This paper is about Page Replacement Algorithms. In a computer operating system that uses paging for virtual memory management, page replacement algorithms decide which memory page to be loaded into the main memory (swap in, write to RAM) when a page of memory needs to be allocated.A virtual memory system requires efficient page replacement algorithms to make a decision which pages to evict from memory in case of a page fault. Many algorithms have been proposed for page replacement. Each algorithm is used to decide on which free page frame, a page is placed and tries to minimize the page fault rate while incurring minimum overhead.
