Due to its random nature, the behavior of this algorithm is quite obviously, ... Additional information about more complex LRU algorithms can found in; [11]. Least Frequently Used (LFU); Often confused with LRU, Least Frequently Used (LFU) selects a page for replacement if it has not been used often in the past.

This way the page replacement algorithm 'samples' the memory usage of the processes in the system every clock tick, rather than every instruction. ... Trouble is that it never forgets---the counter never decreases, so that pages which were used heavily, but are now entirely unused, retain their high frequency count.

The best, offline cache replacement policy is Belady’s MIN that replaces the page that is used farthest in the future [1]. ... LFU replaces the least frequently used page and is optimal under the IRM [5], ... B2). The algorithm sets a target size p for the list T1. The replacement policy is simple: Replace the LRU page in; T1,

== Not Frequently Used == The not frequently used (NFU) page replacement algorithm also requires a counter, but every page has one counter of its own, which is initially zero.
