| Abstract: | We consider a random walk  with the constraint that each coordinate of the walk is at distance one from the following one. In this paper, we show that this random walk is slowed down by a variance factor  with respect to the case of the classical simple random walk without constraint. © 2014 Wiley Periodicals, Inc.
