- A - Completeness: This assesses if the algorithm reliably finds a solution when one is available and correctly indicates failure when no solution exists. This aligns with III.
- B - Cost optimality: This describes the algorithm's capability to identify the solution with the minimum path cost. This aligns with IV.
- C - Time complexity: This quantifies the algorithm's execution duration, typically expressed by the number of states and actions processed. This aligns with I.
- D - Space complexity: This refers to the memory resources needed for the algorithm's operation. This aligns with II.
Step 2: Conclusion.
The correct pairings are: A - III, B - IV, C - I, D - II.
