This work purposes the optimization of Genetic Algorithm by varying its mutation rates to work on a NPHard Problem. BreezySwing. In this algorithm, a variable-length code is assigned to input different characters. Huffman coding uses a specific method for choosing the representation for each symbol, resulting in a prefix code (sometimes called "prefix-free codes", that is, the bit string representing some particular symbol is never a prefix of the bit string representing any other symbol). The full source code is available at GitHub, written using C++11. The term refers to the use of a variable-length code table for encoding a source symbol (such as a character in a file) where the variable-length code table has been derived in a particular way based on the estimated probability of occurrence for each possible. Insertion sort is an in-place sorting algorithm and is efficient algorithm than selection sort and bubble sort. Unlike to ASCII or Unicode, Huffman code uses different number of bits to encode letters. This algorithm is called Huffman coding, and was invented by D. It not only supports features like multiprocessing but does it with ease. Huffman Coding | Greedy Algo-3 Prefix Codes , means the codes (bit sequences) are assigned in such a way that the code assigned to one character is not the prefix of code assigned to any other character. Most importantly, it is an interpreted language, which means that the written code is not actually translated to a computer-readable format at runtime. And there is so much we can do with it to make the code lighter and faster. If the compressed bit stream is 0001, the de-compressed output may be "cccd" or "ccb" or "acd" or "ab".
