In a previous paper we have introduced a new continuation method which does not require an analytical model, but only an experimental time series. Using a predictor-corrector technique the method tracks an unstable orbit of a map, through different bifurcation regimes by varying an accessible system parameter. In this method the continuation parameter was varied deterministically. That is, the location of the parameter at each continuation step is chosen by the experimenter. In this paper we introduce a similar algorithm, but now the parameter is varied randomly. We will refer to this algorithm as random-walk control or stochastic tracking. This algorithm is useful to experimentalists for canceling the effect of drift in experiments, which is always inevitable at some level.
