We compare the efficiency of a deterministic 'lawnmower' and random search strategies for finding a prescribed sequence of letters (a password) of length M in which all letters are taken from the same Q-ary alphabet. We show that, at best, a random search takes two times longer than a 'lawnmower' search.
