The Sharma-Mittal Entropy is Subadditive and Supermodular on the Majorization Lattice

Roberto Bruno, Ugo Vaccaro

We prove that Sharma-Mittal entropy is a subadditive and supermodular function on the lattice of all -dimensional probability distributions, ordered according to the partial ord…

Optimal Binary Variable-Length Codes with a Bounded Number of 1's per Codeword: Design, Analysis, and Applications

Roberto Bruno, Roberto De Prisco, Ugo Vaccaro

In this paper, we consider the problem of constructing optimal average-length binary codes under the constraint that each codeword must contain at most ones, where is a giv…
