2- If the first branch of the tree is completely traversed without finding the goal state, using the technique of depth first where the search should go next? Show your answer in drawing.
3- Iterative search is made to save space compared to depth and breadth search. What you think the time complexity of the technique compared to the two techniques.
4- What are the drawbacks of the hill climbing method?
5- Why the technique of best first search is better than the hill climbing method?
6- In terms of time and space complexity which is better (hill climbing or best first)?
7- In A* algorithm a heuristic function is used to determine the next state. How could you determine the value of this function?
8- Forward reasoning and backward reasoning, what is the difference between them. When should you use backward reasoning in your search?
9- Suppose you want to build a house. Draw the state space tree of the process and assess the values of the heuristic functions at any state.
