... f~(cn). Proof. This proof is really just a generalization of the proof of Theorem 1. It uses, however, the Q subsets in a way that the proof of Theorem 1 does not. First, we drop the n subscript ... let j be the position where the yield of the final value of the current node starts, and let k be the length of that yield. By the algorithm, k <_ m. If...
