Additional Constraints,The coding algorithms presented so far have focussed on minimizing the expected length of a code, and on fast coding speed once a code has been devised. Furthermore, all codes have used a binary channel alphabet. This chapter examines other coding problems.

Static Codes, may be relatively poor, but the simple and regular codewords that they assign can usually be encoded and decoded extremely quickly. Moreover, some compression applications are such that the source probabilities .. have a distribution to which the regular nature of these non-parameterized codes is well suited.

What Next?,be full of effusive optimism, and paint a rosy picture of what the book is intended to achieve. But by the time your reader reaches the final chapter there is no scope for lily-gilding, and for better or for worse, they have formed an opinion as to the validity and usefulness of your work.

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”?

https://doi.org/10.1007/978-3-030-94759-0 as described in Chapter 4 is the best that can be done using integral-length codewords, it would thus appear that a minimum-redundancy code obtains compression as close to the entropy as can be achieved.
