On the proportion of prefix codes in the set of three-element codes

Adam Woryna

Let $L$ be a finite sequence of natural numbers. In Woryna (2017,2018), we derived some interesting properties for the ratio $ρ_{n, L} = ∣ P R_{n} (L) ∣/∣ U D_{n} (L) ∣$ , where $U D_{n} (L)$ denotes…

On the ratio of prefix codes to all uniquely decodable codes with a given length distribution

Adam Woryna

We investigate the ratio $ρ_{n, L}$ of prefix codes to all uniquely decodable codes over an $n$ -letter alphabet and with length distribution $L$ . For any integers $n \geq 2$ and $m\g…

On groups generated by bi-reversible automata: the two-state case over a changing alphabet

Adam Woryna

The notion of an automaton over a changing alphabet $X = (X_{i})_{i \geq 1}$ is used to define and study automorphism groups of the tree $X^{*}$ of finite words over $X$ . The concept of b…
