Abstract: Consider a random process on a graph. Given only a snapshot of the set of visited sites at some time, how easy is it to guess the starting point? I will present ideas and problems related to this question in two contexts: disease transmission/rumor spread on a social network, and simple random walk/Brownian motion.
