Optimal page replacement program in c++
WebDec 20, 2024 · When a page needs to be replaced, the operating system chooses the page which is least frequently used for the replacement with the incoming page. We will use C++ to write this algorithm due to the standard template library support. Hence, we will write the program of LFU Page Replacement Algorithm in C++, although, it’s very similar to C. INPUT: WebOptimal Page Replacement algorithm → this algorithms replaces the page which will not be referred for so long in future. Although it can not be practically implementable but it can be used as a benchmark. Other algorithms are compared to this in terms of optimality.
