Let us learn how to implement LFU Page Replacement Algorithm in C programming language. This code for Least Frequently Used Page Replacement makes use of Arrays.
What is LFU Page Replacement Algorithm?
In LFU Page Replacement method, the page with the minimum count is selected for replacement with the page that needs to enter into the system.
LFU is a cache algorithm which is used to manage computer’s memory. A counter is assigned to every block of memory that is loaded into the cache memory.
However, the LFU technique is hardly implemented these days but this algorithm is normally combined with other algorithms which make it a hybrid algorithm, and then it is implemented.
LFU algorithm is sometimes also combined with LRU replacement algorithm, and then implemented.
