we have a project in our class to design a sliding numbers game similar to this one: http://www.eatmygames.com/gameinfo.asp?id=24puzzle
the only difference is that the number of blank spaces is user input (max=n/2 where n: no of elements in a row/column).
we have to design an algorithm to make the computer solve the puzzle on its own.
can we get some ideas for the AI part? we're totally stumped!
PS: I know this counts as homework, but I just need a hint for the algorithm. we can take it from there onwards.
