Legend tells us that Alexander the Great visited the city of Gordia, in asia minor, before he conquered most of the known world. The shrine in the city held an oxcart that was fastened to a pole using an intricate knot with no loose ends. It had been prophesied that the one who could solve this Gordian knot would become the king of the world. The Alexander solution to the problem of the Gordian knot has become a timeless metaphor for the solution of intractable problems. It was, according to himself, his greatest victory.
There are actually two different solutions to the Gordian knot with somewhat different implications. Aristobulus tells us that Alexander removed the pole from the oxcart and thereby exposed the loose end of the knot. This implies that sometimes, the way forwards is to look for a clever shortcuts that cut through all the difficult steps. The other account, the classical one, from Plutarch tells us that Alexander used his sword and cut the knot in two. This would invite us to look for an elegant out of the box solution, simple and resolute or perhaps even a brute force solution. The key to either of these solutions is to look at the problem from a new perspective or to redefine the goal.
