Optimal Page Replacement Algorithm C Program

C Program For Optimal Page Replacement Algorithm

Learn How To Implement Optimal Page Replacement Algorithm in C Programming Language. This code for Optimal Page Replacement makes use of Arrays.

What is Optimal Page Replacement Algorithm?

The page replacement algorithms are used in Operating Systems that use Virtual Memory Management. When a page of memory needs to be allocated to the CPU, these page replacement algorithms decide which pages should be written to the disk and which algorithms should be swapped out of memory.

This algorithm is also known as Clairvoyent Replacement Algorithm. As per the optimal page replacement technique, the page with the highest label should be removed first. When a page needs to be swapped into the memory, the OS will swap out the page which is not required to be used in the near future.

This page replacement algorithm is a little unreliable to implement and, therefore, it cannot be implemented in a general purpose operating system.

    The Optimal Page Replacement Algorithm can offer near optimal performance, but not on the first execution of the program.
