In information theory, an entropy coding (or entropy encoding) is any lossless data compression method that attempts to approach the lower bound declared by Shannon's source coding theorem, which states that any lossless data compression method must have an expected code length greater than or equal to the entropy of the source.
In the field of data compression, Shannon coding, named after its creator, Claude Shannon, is a lossless data compression technique for constructing a prefix code based on a set of symbols and their probabilities (estimated or measured).
Unfortunately, Shannon–Fano coding does not always produce optimal prefix codes; the set of probabilities {0.35, 0.17, 0.17, 0.16, 0.15} is an example of one that will be assigned non-optimal codes by Shannon–Fano coding. Fano's version of Shannon–Fano coding is used in the IMPLODE compression method, which is part of the ZIP file format ...
In information theory, Shannon–Fano–Elias coding is a precursor to arithmetic coding, in which probabilities are used to determine codewords. [1] It is named for Claude Shannon , Robert Fano , and Peter Elias .
In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression.The process of finding or using such a code is Huffman coding, an algorithm developed by David A. Huffman while he was a Sc.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes".

For much of Huffman's tenure, the show's set was bleachers or benches for children against a backdrop mural of cartoon characters, mostly those from Looney Tunes. Special episodes were occasionally done on location, in area shopping malls or as part of large local events, like the annual Sternwheeler Regatta.
The debut broadcast of "Ice" was watched by 10 million viewers in 6.2 million households. The episode received positive reviews at large from critics, who praised its tense atmosphere. The plot of the episode shows FBI agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) investigating the deaths of an Alaskan research team
