Ranking at depth 6
Model's reasoning and response:
To solve this problem, we need to evaluate each state against the goal state, which is:

- Curb_0 has car_0
- Curb_1 has car_1
- Curb_2 has car_2
- Curb_3 has car_3

Let's analyze each state:

### State 36
- **Curb_0**: car_0 (Correct)
- **Curb_1**: Empty (Incorrect)
- **Curb_2**: car_3 with car_2 double parked (Incorrect)
- **Curb_3**: car_1 (Incorrect)

**Constraints Satisfied**: 1 (Curb_0)

### State 39
- **Curb_0**: car_0 (Correct)
- **Curb_1**: car_2 (Incorrect)
- **Curb_2**: car_3 (Incorrect)
- **Curb_3**: car_1 (Incorrect)

**Constraints Satisfied**: 1 (Curb_0)

### State 44
- **Curb_0**: car_0 (Correct)
- **Curb_1**: car_2 with car_1 double parked (Incorrect)
- **Curb_2**: car_3 (Incorrect)
- **Curb_3**: Empty (Incorrect)

**Constraints Satisfied**: 1 (Curb_0)

### State 45
- **Curb_0**: car_0 (Correct)
- **Curb_1**: Empty (Incorrect)
- **Curb_2**: car_3 with car_2 double parked (Incorrect)
- **Curb_3**: car_1 (Incorrect)

**Constraints Satisfied**: 1 (Curb_0)

### State 48
- **Curb_0**: car_0 with car_3 double parked (Incorrect)
- **Curb_1**: car_2 (Incorrect)
- **Curb_2**: Empty (Incorrect)
- **Curb_3**: car_1 (Incorrect)

**Constraints Satisfied**: 0

### Ranking
All states except State 48 satisfy 1 constraint. State 48 satisfies none. Therefore, the ranking is based on the number of constraints satisfied:

```ranking
36, 39, 44, 45, 48
```

All states except State 48 are equally close to the goal, satisfying 1 constraint. State 48 is the least favorable as it satisfies none.

Final ranking:
