The first is a lower bound on the expected length of a code: Shannon’s . limit. The second restriction applies to the lengths of codewords, and is generally referred to as the

Attractiveness and Opportunitieshow, its set of codeword lengths better matches the probability distribution than do the other two sets. Which forces the question: given a sorted list of symbol probabilities, how can a set of prefix-free codewords be assigned that is best for that data? And what is really meant by “best”?

While there was some discussion of alternative ways of representing the prelude in a semistatic system such as those of Algorithm 4.6 on page 83 and Algo
