Abstract: The problem of how many trajectories of a random walker in a potential areneeded to reconstruct the values of this potential is studied. We show thatthis problem can be solved by calculating the probability of survival of anabstract random walker in a partially absorbing potential. The approach isillustrated on the discrete Sinai random force model with a drift. Wedetermine the parameter temperature, duration of each trajectory,

. valuesmaking reconstruction as fast as possible.
