The Great Lempel-Ziv vs. Arithmetic Coding Debate

In order to do something different, this session will be arranged in the form of "The Great Lempel-Ziv vs. Arithmetic Coding Debate". Therefore participation to this class is obligatory except for a very good reason that should be mailed beforehand to Tomi and Petri.

For the debate, half of the people will be defending the use of arithmetic coding and the rest universal coding based on Lempel-Ziv coding. The point is to argue about the use of the methods from pragmatic point of view, i.e., why in practice one should prefer one method over the other. The debate will be structured as follows:

1) The defending groups will select among themselves people to give a brief 10 minute introduction (2-3 transparencies) to the method in question.

2) Both parties will present a list (5 items or more) of reasons why their method is better than the competing one.

3) A discussion will be intiated and hopefully lively continued.

The group assignments are as follows, and will not be changed without strong supporting argumentation:

Team Lempel-Ziv:

Team Arithmetic coding:
