For part B, draw a solution that follows the Plan Space Planning Partial Plan

### Planning Problem: Interchanging Variable Values

**Objective:**
Interchange the values of two variables, v1 and v2.

**Initial State:**
- Value(v1, 3)
- Value(v2, 5)
- Value(v3, 0)

**Goal:**
- Value(v1, 5)
- Value(v2, 3)

**Actions:**
- **Assign(V, W, X, Y):**
  - Preconditions: 
    - Value(V, X)
    - Value(W, Y)
  - Effects: 
    - Value(V, Y)
    - ¬Value(V, X)

### Plan Space Planning Partial Plan

The diagram represents a partial plan illustrating the transformation steps involving actions to achieve the goal states.

- **Nodes and Edges:**
  - **Start Node (a₀):** Represents the initial state.
  - **End Node (a∞):** Represents the goal state.

- **Processes:**
  1. **Assign(v1, v2, 3, 5):**
     - Input: 
       - value(v1, 3)
       - value(v2, 5)
     - Output:
       - value(v1, 5) 

  2. **Assign(v2, w, x, 3):**
     - Transitions v2 from an intermediary state to the goal state.

- **Links:**
  - Dashed arrows indicate preconditions for the actions and establish effects required to reach the end state.

### Tasks

a. **List All Flaws (Open Goals and Threats) in this Partial Plan:**
   - Identify and list any preconditions not satisfied.
   - Address any potential threats to achieving the goal state.

b. **Draw 1 Possible Solution Starting with the Above Partial Plan:**
   - Illustrate a sequence of actions that fulfills all preconditions and resolves threats, leading to the goal state.
