The number of samples sufficient to guarantee that f_{k } p_{k} < ε with confidence 1  p, for all 0 ≤ k < K, in the application RNAborSample. Here , the Boltzmann probability, as computed exactly by RNAbor, for a kneighbor of S_{0}, and f_{k }is the relative frequency of kneighbors among N sampled structures.
