Stack algorithms can never exhibit Belady's anomaly.

Question

Quizplus · Accepted Answer

Stack algorithms follow the Last-in-First-Out (LIFO) principle for replacing pages, which means the page that was most recently used is the last to be replaced. This ensures that the pages that are more likely to be used again in the near future remain in the memory. Therefore, stack algorithms do not exhibit Belady's anomaly, which is a phenomenon where increasing the size of the memory can lead to an increase in the number of page faults.
