Abstract
We propose a generic algorithm for the construction of efficient reversible variable-length codes (RVLCs) and variable-length error-correcting (VLEC) codes, which optimizes the codeword length distribution. The algorithm may be applied to any existing codeword selection mechanism, and it is capable of generating codes of higher efficiency in comparison to the algorithms disseminated in the literature.
