Local Search (constraint Satisfaction) - Random Walk

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:

    And catch the gleaming of a random light,
    That tells me that the ship I seek is passing, passing.

    This melancholy London—I sometimes imagine that the souls of the lost are compelled to walk through its streets perpetually. One feels them passing like a whiff of air.
