To solve the puzzle, the numbers must be rearranged into order. The 15-puzzle (also called Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square and many others) is a sliding puzzle that consists of a frame of numbered square tiles in random order with one tile missing. The puzzle also exists in other sizes, particularly the smaller 8-puzzle.
How are heuristics used in the n puzzle?
The n puzzle is a classical problem for modelling algorithms involving heuristics. Commonly used heuristics for this problem include counting the number of misplaced tiles and finding the sum of the taxicab distances between each block and its position in the goal configuration.
When does a puzzle need to be solvable?
In particular, if the empty square is in the lower right corner then the puzzle is solvable if and only if the permutation of the remaining pieces is even. Johnson & Story (1879) also showed that the converse holds on boards of size m × n provided m and n are both at least 2: all even permutations are solvable.
