## Exercise: Retrieval by Nearest

## Exercise: Recording Cases in Real Life

- the new problem is to find the route from Q to the arrow pointed destination.
- D is the correct answer since it starts close to Q and ends close to the arrow

## Nearest Neighbor for Complex Problems

When there are K dimensions of elements, the formula needs to be generalized.
**Limitation of the method**:

- in real life, N can be really large
- the nearest method might be the great solution.
