About the 15 puzzle solver
==========================

Game description : A 4X4 Matrix is provided consisting of 16 cells. Of these 15 cells are filled in an arbitary fashion with the first natural numbers. One cell is kept empty. The horizontal or vertical neighbours of the empty cell can swap their positions with it. This accounts for one move. The objective is to arrange the numbers in increasing order in a row major fashion by proceeding through a  series of such moves. Provision is there in the program to display each  intermediate configuration of the matrix and a counter for number of moves taken. Note that however only 50% of the cases are solvable.. this is true because it is a bounded region of 4x4 matrix and we are not allowed to lift the numbers out of the frame. 

 We have presented the user with the option of playing 15 puzzle for any combination of his choice or to let the solver solve it for him. If the player gets stuck up somewhere in the middle of playing the game, he can ask the solver to solve it for him, from that point onwards. Advanced players can actually compete with the computer to solve it in the minimum number of moves! 

 Our program is the first of it's kind and is therefore very unique.
It's the only software that offers an automatic solution for any given combination of numbers!! The actual strength of our game is in using artificial intelligence to solve any given combination of the input. With this, the user can actually test his IQ by competing with the computer to solve the puzzle in the least number of moves. This will surely boost his IQ and take it to the next level!
