Well, a backtracking algorithm means working toward a solution, and, when you reach a dead end, going back to the last time you made a "choice". In many computer science classes students learn to implement a backtracking algorithm by solving the "Eight Queens Problem". You can google for that or check a CS text.
The reason this is "inverse" is because you are starting with the "solution". I think that would be faster and easier to write, personally, but I might be wrong.
