k-ary Huffman coding

(algorithm)

Definition: A minimal variable-length coding based on the frequency of each character. Similar to a Huffman coding, but joins k trees into a k-ary tree at each step, and uses k symbols for each level.

Note: The coding at each stage has k symbols, not just 2 (0 or 1) like traditional Huffman. If k is a power of two, that is, k=2n, every symbol can be represented by n bits.
