The number of nodes expanded during the A* search is? (Enter - 1 if the search took too long) Consider the 8-sliding tile puzzle with the initial state: 231 457 86 and the usual goal state: 1 2 3 456 78 What is the number of expanded nodes/paths during a A* search, breadth-first graph search, and depth-first graph search when using the code in search.py? Hint: astar_search(problem, h=None, display=False) (https://github.com/aimacode/aima- python/blob/master/search.py#L415) already has a "display" parameter that can be set to True to print the number of expanded nodes at the end. eight_puzzle = EightPuzzle(??) print(astar_search(eight_puzzle, h=None, display=True).solution()) For breadth-first search(https://github.com/aimacode/aima-python/blob/master/search.py#L238) and depth-first search(https://github.com/aimacode/aima-python/blob/master/search.py#L216), you will have to add a similar "display" parameter to those functions to print the number of expanded nodes.
