WebbShannon-Fano coding: list probabilities in decreasing order and then split them in half at each step to keep the probability on each side balanced. Then codes/lengths come from resulting binary tree. My question is whether one of these algorithms always provides a better L = ∑ p i l i? In a few examples I've done, Shannon-Fano seems better.
