Anybody recall a discussion from any AI literature on a
heuristic for deciding which tile to move next in the
8-tile puzzle?  

In this puzzle, there are 9 locations for tiles: 8 actual
tiles, and one empty space.  The tiles are out of order,
and the user has to sort the tiles by repeatedly moving a tile
into the empty space.

Anyone seen a Prolog program that does this? A friend of mine
wants to see what happens when you apply it to a 15-tile puzzle.
