# MRU (Most Recently Used)
## Goal
Evict the most recently accessed entry.
## Implementation
If you already have an LRU structure (recency-ordered list):
- LRU victim is the tail
- MRU victim is the head
So MRU is typically “LRU, but evict from head instead of tail”.
## Notes
MRU is only beneficial for specific cyclic patterns; it is not a safe default.
