Question
Write a program which performs iterative deepening depth first search (Figure 3.12, AIMA
4th edition) to find the solution to any given board position for 15 puzzle
Input
The input should be given in the form of a sequence of numbered tiles for initial board
configuration, '0' indicating the empty space.
Output
1. Moves
2. Number of Nodes expanded
3. Time Taken
4. Memory Used
Hint
Algorithm 3.12 mentions a function is_cycle(node) to check for cycle in the graph. You can
traverse a current node all the way to the root node using pointer to the parent, and keep track
of seen node in a hash set. If the current node is same as one its ancestor, then cycle is
detected.
