Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Imagine a system where the access pattern is completely randomized. Propose how LFU would perform in this situation. Provide an explanation.

💡 Hint: Think about how a random pattern impacts frequency counts.

Challenge 2 Hard

Evaluate a workload scenario where pages have a predictable temporal locality. Compare how LFU vs. MFU would perform.

💡 Hint: Consider how predictable patterns align with each algorithm's strengths.
