Description

The site has two AVs, one for encoding and one for decoding. The one for encoding shows most of the material. This AV is a slideshow walking through an example of huffman coding.

Evaluation

Good, clear presentation. It would be better if during build, the separate trees were re-ordered when the combined value becomes greater than other items ahead of it on the list (in other words, the list should stay sorted). This not only reflects an important detail in real implementations, but it also would be less confusing not to have tree pointers crossing each other unnecessarily.

HowToUse

For detailed instructions on how to install Animal and run Animal AVs, see: http://www.algoanim.info/Animal2/?q=node/290. Once you have installed the Animal .jar file and downloaded/unpacked the .zip file of Animal animations, you are now ready to run Animal. Run the .jar file to start Animal. Then go to the "Open" menu item, and browse to where you put the animal animations you got in the .zip file. Pick this AV from the list. You can then step through the animation, or use "kiosk mode" to have the steps fed to you at a constant pace.
