Ranking at depth 12
Model's reasoning and response:
To rank the states, we need to evaluate how many of the goal constraints are satisfied in each state. The goal constraints are:

1. Passenger p0 needs to be on floor 0.
2. Passenger p3 needs to be on floor 0.
3. Passenger p2 needs to be on floor 2.
4. Passenger p5 needs to be on floor 2.
5. Passenger p1 needs to be on floor 3.
6. Passenger p4 needs to be on floor 3.

Let's evaluate each state:

### State 117
- p0: Floor 1 (not satisfied)
- p3: Floor 4 (not satisfied)
- p2: Floor 2 (satisfied)
- p5: Floor 2 (satisfied)
- p1: Floor 3 (satisfied)
- p4: Floor 1 (not satisfied)

**Constraints satisfied: 3 (p2, p5, p1)**

### State 119
- p0: Floor 1 (not satisfied)
- p3: Floor 4 (not satisfied)
- p2: Floor 2 (satisfied)
- p5: Floor 2 (satisfied)
- p1: Floor 3 (satisfied)
- p4: Floor 1 (not satisfied)

**Constraints satisfied: 3 (p2, p5, p1)**

### State 120
- p0: Floor 1 (not satisfied)
- p3: Floor 4 (not satisfied)
- p2: Floor 2 (satisfied)

**Constraints satisfied: 3 (p2, p5, p1)**

### State 123
- p0: Floor 0 (satisfied)
- p3: Floor 4 (not satisfied)
- p2: Floor 4 (not satisfied)
- p5: Floor 2 (satisfied)
- p1: Floor 3 (satisfied)
- p4: Floor 1 (not satisfied)

**Constraints satisfied: 3 (p0, p5, p1)**

### State 126

- p3: Floor 0 (satisfied)
- p2: Floor 4 (not satisfied)
- p5: Floor 2 (satisfied)
- p1: Floor 3 (satisfied)
- p4: Floor 1 (not satisfied)

**Constraints satisfied: 3 (p3, p5, p1)**

### State 129
- p0: Floor 0 (satisfied)
- p3: Floor 4 (not satisfied)
- p2: Floor 4 (not satisfied)
- p5: Floor 2 (satisfied)
- p1: Floor 3 (satisfied)
- p4: Floor 1 (not satisfied)

**Constraints satisfied: 3 (p0, p5, p1)**

### State 130
- p0: Floor 0 (satisfied)
- p3: Floor 4 (not satisfied)
- p2: Floor 4 (not satisfied)
- p5: Floor 2 (satisfied)
- p1: Floor 3 (satisfied)
- p4: Floor 1 (not satisfied)

**Constraints satisfied: 3 (p0, p5, p1)**

### State 131
- p0: Floor 0 (satisfied)
- p3: Floor 4 (not satisfied)
- p2: Floor 4 (not satisfied)
- p5: Floor 2 (satisfied)
- p1: Floor 3 (satisfied)
- p4: Floor 1 (not satisfied)

**Constraints satisfied: 3 (p0, p5, p1)**

### Ranking
All states satisfy 3 constraints, so they are equally ranked. However, if we consider the proximity to satisfying additional constraints, we can rank them based on the potential to satisfy more constraints with minimal moves. For simplicity, we will rank them based on the order they were presented, as they all satisfy the same number of constraints.
