Answer:A
Explanation: None. 6. Which algorithm is in more similar to backward chaining algorithm?
A. Depth-first search algorithm B. Breadth-first search algorithm C. Hill-climbing search algorithm D. All of the mentioned
Explanation: It is depth-first search algorithm because its space requirements are linear in the size of the proof. 7. Which problem can frequently occur in backward chaining algorithm?
