In mathematics, a random walk is a random process that describes a path that consists of a succession of random steps on some mathematical space. An elementary example of a random walk is the random walk on the integer number line which starts at 0, and at each step moves +1 or −1 with equal probability. Other examples include the path traced by a molecule as it travels i… WebThe designation “random walk” seems apt, since a realization of the process describes the path of a person (suitably intoxicated) moving randomly one step forward or backward. …
