Coding theory

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 symbol by symbol. With the right coding strategy an independent and identically-distributed source may be compressed almost arbitrarily close to its entropy. This is in contrast to fixed length coding methods, for which data compression is only possible for large blocks of data, and any compression beyond the logarithm of the total number of possibilities comes with a finite (though perhaps arbitrarily small) probability of failure. Some examples of well-known variable-length coding strategies are Huffman coding, Lempelโ€“Ziv coding, arithmetic coding, and context-adaptive variable-length coding. (Wikipedia).

How to determine if an expression is a monomial, binomial, or trinomial

๐Ÿ‘‰ Learn how to classify polynomials. A polynomial is an expression of the sums/differences of two or more terms having different interger exponents of the same variable. A polynomial can be classified in two ways: by the number of terms and by its degree. A monomial is an expression of 1
