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.

Famous quotes containing the words random and/or walk:
“... the random talk of people who have no chance of immortality and thus can speak their minds out has a setting, often, of lights, streets, houses, human beings, beautiful or grotesque, which will weave itself into the moment for ever.”
—Virginia Woolf (1882–1941)
“When children dress like adults they are more likely to behave as adults do, to imitate adult actions. It is hard to walk like an adult male wearing corduroy knickers that make an awful noise. But boys in long pants can walk like men, and little girls in tight jeans can walk like women.”
—David Elkind (20th century)
