Ranking at depth 16
Model's reasoning and response:
To solve this problem, we need to evaluate each state against the goal state, which requires:

- Curb_0 to have car_0
- Curb_1 to have car_1
- Curb_2 to have car_2
- Curb_3 to have car_3

Let's evaluate each state:

### State 141
- Curb_0: car_0 (Correct)
- Curb_1: car_2 (Incorrect)
- Curb_2: car_3 (Incorrect)
- Curb_3: car_1 (Incorrect)

**Constraints satisfied: 1**

### State 142
- Curb_0: car_0 (Correct)
- Curb_1: car_2 (Incorrect)
- Curb_2: Empty (Incorrect)
- Curb_3: car_1 (Incorrect)

**Constraints satisfied: 1**

### State 143
- Curb_0: car_0 (Correct)
- Curb_1: car_2 (Incorrect)
- Curb_2: car_3 (Incorrect)
- Curb_3: car_1 (Incorrect)

**Constraints satisfied: 1**

### State 144
- Curb_0: car_0 (Correct)
- Curb_1: car_2 (Incorrect)
- Curb_2: car_3 (Incorrect)
- Curb_3: car_1 (Incorrect)

**Constraints satisfied: 1**

### State 147
- Curb_0: car_0 (Correct)
- Curb_1: car_2 (Incorrect)
- Curb_2: car_3 (Incorrect)
- Curb_3: car_1 (Incorrect)

**Constraints satisfied: 1**

### Ranking
All states satisfy only one constraint, so they are equally close to the goal state. Therefore, the ranking is arbitrary among them.

```ranking
141, 142, 143, 144, 147
```

Each state has one correct car in the correct curb, so they are all equally ranked.
