New page

Asymmetric Numeral Systems (ANS) are an entropy-based encoding method
introduced by Jarek Duda in 2013, combining the Shannon-optimal
compression ''effectiveness'' of arithmetic coding with the
execution ''efficiency'' of Huffman coding. Existing presentations
of the ANS encoding and decoding algorithms are somewhat obscured by
the lack of suitable presentation techniques; I will present an
equational derivation, calculational where it can be, and highlighting
the creative leaps where it cannot.
