State Space Approach

The **State Space Approach** follows a series of logical steps for problem-solving. These steps are: - **A. Identify the set of rules (all possible actions):** The first step is to define all the possible actions that can be taken to move from one state to another. - **B. Describe the states:** After identifying the possible actions, we need to describe the states in which the system can exist. States represent different configurations of the system during problem-solving. - **C. Identify the initial state followed by the goal state:** In this step, we define the starting point (initial state) and the destination (goal state) of the system. - **D. Find the solution path in the state space:** Finally, once we have the initial state and goal state defined, we search for the path in the state space that leads from the initial state to the goal state. Step 2: Conclusion.
The correct order of steps is: **A (Identify rules), B (Describe states), C (Identify initial and goal states), D (Find the solution path)**. Thus, the correct answer is **(2) A, B, C, D**.
