Huffman: construction of minimum-redundancy codes

What changed

Constructed an optimal prefix-code algorithm for given finite symbol weights.

Scientific scope

The record is Huffman’s sole-author 1952 Proceedings of the IRE paper. It does not absorb Shannon’s source-coding theory, later adaptive or canonical variants, or every compression system that uses Huffman coding.
