Scheme is a dialect of the Lisp family of programming languages.Scheme was created during the 1970s at the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) and released by its developers, Guy L. Steele and Gerald Jay Sussman, via a series of memos now known as the Lambda Papers.
Double-block-length methods make hashes with double the hash size compared to the block size of the block cipher used. So a 128-bit block cipher can be turned into a 256-bit hash function. These methods are then used inside the Merkle–Damgård construction to build the actual hash function. These methods are described in detail further down.

In the early 1990s, lossy compression methods began to be widely used. [14] In these schemes, some loss of information is accepted as dropping nonessential detail can save storage space. There is a corresponding trade-off between preserving information and reducing size. Lossy data compression schemes are designed by research on how people ...

One such method is the famous Babylonian method, which is given by x k+1 = (x k + 2/x k)/2. Another method, called "method X", is given by x k+1 = (x k 2 − 2) 2 + x k. [note 1] A few iterations of each scheme are calculated in table form below, with initial guesses x 0 = 1.4 and x 0 = 1.42.

For a polynomial-time list-decoding algorithm to exist, we need the combinatorial guarantee that any Hamming ball of radius around a received word (where is the fraction of errors in terms of the block length ) has a small number of codewords.
