The Asymmetric Numeral System (ANS) is a new entropy compression method that the
industry has highly valued in recent years. ANS is valued by the industry precisely because …

A crucial task in the design of an efficient ANS encoder consists in choosing a favourable
symbol distribution. This task seems to be hard, due to its combinatorial nature, in particular …

Data storage is an indispensable part of data management system. Asymmetric numeral
systems (ANS) is a widely used compression algorithm. A number of implementations, such …

Asymmetric Numeral Systems (ANS) are a family of entropy coders for information sources
with a finite alphabet, and usually require approximating the source distribution to rational …

Nowadays entropy encoders are part of almost all data compression methods, with the
Asymmetrical Numeral Systems (ANS) family of entropy encoders having recently risen in …

An entropy coder is defined to be asymptotically optimal if it attains asymptotically the source
entropy in a certain limit of its parameter. In this paper, we first give a sufficient condition for a …
