Implement functions DFS_limited(board, max_depth) DFS_iterative_deepening(initial_state) Modify your program so you can easily change board size. Change hard coded size 3 to a variable BOARD_SIZE. * Submit your '8-puzzle.py' to Blackboard 3. Test your 8-puzzle for multiple initial states (use random_shuffle to create initial states) with board size = 3 and with board size = 4 Compare your algorithms. random-search vs. BFS vs. DFS vs. AStar.
