List decoding is a method in coding theory that extends the concept of traditional decoding of error-correcting codes. In classical decoding, the goal is to recover the original message from a received codeword, assuming that the codeword has been corrupted by noise. When using list decoding, however, the decoder generates a list of all messages that are within a certain distance of the received codeword, rather than just trying to find a single most likely message.
