Using Probabilistic Models for Data Compression
Mathematics, 2022 Our research objective is to improve the Huffman coding efficiency by adjusting the data using a Poisson distribution, which avoids the undefined entropies too. The scientific value added by our paper consists in the fact of minimizing the average length

Space-efficient Huffman codes revisited
Information Processing Letters, 2023 Canonical Huffman code is an optimal prefix-free compression code whose codewords enumerated in the lexicographical order form a list of binary words in non-decreasing lengths. Gagie et al. (2015) gave a representation of this coding capable to encode or decode a symbol in constant worst case time. It uses $σ\lg \ell_{\text{max}} + o(σ) + O(\ell_{\text{
