WebIn a computer operating system that uses paging for virtual memory management, page replacement algorithms decide which memory pages to page out, sometimes called swap out, or write to disk, when a page of memory needs to be allocated. WebVarious page replacement Strategies / Algorithms. The Optimal Page Replacement Algorithm − This algorithm replaces the page that will not be used for the longest period of time. The moment the page fault occurs, some set of pages are in memory. One of these page will be referenced on the very next instruction.

There are a variety of page replacement algorithms: The theoretically optimal page replacement algorithm (also known as OPT, clairvoyant replacement algorithm, or Bélády's optimal page replacement policy) is an algorithm that works as follows: when a page needs to be swapped in, the operating system swaps out the page whose next use will occur farthest in the future.
