page replacement algorithms: optimal, FIFO, and LRU

WebIn computer science, an algorithm is said to be asymptotically optimal if, roughly speaking, for large inputs it performs at worst a constant factor (independent of the input size) worse than the best possible algorithm. It is a term commonly encountered in computer science research as a result of widespread use of big-O notation . WebThis access varies per the runtime workload of the OS. If we can clearly see access patterns and can predict future required pages, then 'optimal page replacement' is the best. As mentioned by sanjay in the other answer, it minimizes page faults. If the pattern cannot be predicted, LRU could be decent for most of the real-world workloads.
