Variable-length code — In coding theory a variable length code is a code which maps source symbols to a variable number of bits. Variable length codes can allow sources to be compressed and decompressed with zero error (lossless data compression) and still be read back … Wikipedia
Variable-order Markov model — Variable order Markov (VOM) models are an important class of models that extend the well known Markov chain models. In contrast to the Markov chain models, where each random variable in a sequence with a Markov property depends on a fixed number… … Wikipedia
Huffman coding — Huffman tree generated from the exact frequencies of the text this is an example of a huffman tree . The frequencies and codes of each character are below. Encoding the sentence with this code requires 135 bits, as opposed of 288 bits if 36… … Wikipedia
Arithmetic coding — is a method for lossless data compression. Normally, a string of characters such as the words hello there is represented using a fixed number of bits per character, as in the ASCII code. Like Huffman coding, arithmetic coding is a form of… … Wikipedia
Shannon's source coding theorem — In information theory, Shannon s source coding theorem (or noiseless coding theorem) establishes the limits to possible data compression, and the operational meaning of the Shannon entropy.The source coding theorem shows that (in the limit, as… … Wikipedia
Hard coding — (also, hard coding or hardcoding) refers to the software development practice of embedding input or configuration data directly into the source code of a program or other executable object, or fixed formatting of the data, instead of obtaining… … Wikipedia

Prefix code — A prefix code is a code, typically a variable length code, with the prefix property : no code word is a prefix of any other code word in the set. A code with code words {0, 10, 11} has the prefix property; a code consisting of {0, 1, 10, 11} does … Wikipedia
Algorithmic efficiency — In computer science, efficiency is used to describe properties of an algorithm relating to how much of various types of resources it consumes. Algorithmic efficiency can be thought of as analogous to engineering productivity for a repeating or… … Wikipedia
