Grammar-based codes are compression algorithms based on the idea of constructing a context-free grammar for the string to be compressed. Examples include universal lossless data compression algorithms proposed in Kieffer and Yang 2000, and SEQUITUR(http://sequitur.info/), among others. To compress a data sequence, a grammar-based code first transforms into a context-free grammar , and then uses an arithmetic coding algorithm to compress the grammar . For a detailed description of grammar-based codes and context-free grammars, the reader is referred to Kieffer and Yang 2000.
