Random Walk
A random walk algorithm sometimes moves like a greedy algorithm but sometimes moves randomly. It depends on a parameter, which is a real number between 0 and 1. At every move, with probability the algorithm proceeds like a greedy algorithm, trying to maximally decrease the cost of the assignment. With probability, however, the solution is changed in some other way, which involves some degree of randomness.
