Q. You have devised a fresh page-replacement algorithm that you think may be optimal. In a few contorted test cases Belady's anomaly occurs. Is the fresh algorithm optimal? Describe your answer.
Answer: No An optimal algorithm will not undergo from Belady's anomaly for the reason that-by definition-an optimal algorithm replaces the page that will not be used for the longest time. Belady's anomaly take places when a page-replacement algorithm evicts a page that will be essential in the immediate future. An optimal algorithm wouldn't have selected such a page.
