Ariadne's Thread

In ancient Greek Mythology, Theseus used a thread woven by Ariadne, daughter of King Minos of Crete, to find his way out of the labyrinth, after slaying the Minotaur.

The principle of laying down a thread that you can later use to retrace your steps is the same principle at the core of most brute force solving techniques.

The solver may make a guess at the value in a cell and follow it to it's logical conclusion. If the conclusion is invalid, the thread is followed back to the starting point and another guess is tried.

Keywords: brute force, cell, value
