On the Commutative Equivalence of Algebraic Formal Series and Languages [PDF]

open access: closedInternational Journal of Foundations of Computer Science, 2021
The problem of the commutative equivalence of context-free and regular languages is studied. Conditions ensuring that a context-free language of exponential growth is commutatively equivalent with a regular language are investigated.

CoCEC: An Automatic Combinational Circuit Equivalence Checker Based on the Interactive Theorem Prover

open access: yesComplexity, 2021
Checking the equivalence of two Boolean functions, or combinational circuits modeled as Boolean functions, is often desired when reliable and correct hardware components are required.

Algebraic Structure of Combined Traces [PDF]

open access: yesLogical Methods in Computer Science, 2013
Traces and their extension called combined traces (comtraces) are two formal models used in the analysis and verification of concurrent systems. Both models are based on concepts originating in the theory of formal languages, and they are able to capture

Translation Strategies and Equivalence in Formal Document Translation: A Study of UNESCO Agreements

open access: yesJournal of Languages and Language Teaching
This research investigates translation strategies and equivalence in translating Indonesian cultural terms in UNESCO agreements into English. The study aims to explore how translation strategies are adapted to address challenges in formal document ...

Aperiodicity, Star-freeness, and First-order Logic Definability of Operator Precedence Languages [PDF]

open access: yesLogical Methods in Computer Science, 2023
A classic result in formal language theory is the equivalence among non-counting, or aperiodic, regular languages, and languages defined through star-free regular expressions, or first-order logic.

Pushdown Automata and Context-Free Grammars in Bisimulation Semantics [PDF]

open access: yesLogical Methods in Computer Science, 2023
The Turing machine models an old-fashioned computer, that does not interact with the user or with other computers, and only does batch processing. Therefore, we came up with a Reactive Turing Machine that does not have these shortcomings. In the Reactive

Equivalence of the schemes of programs based on the algebraic approach to setting the semantics of programming languages

open access: yesРоссийский технологический журнал, 2022
Objectives. The paper deals with the equivalence of program schemes. According to A.A. Lyapunov and Yu.I. Yanov, the founders of this theory, a program scheme is understood as a program model wherein abstraction from contensive values of operators and ...

Motivation of Word Formation in Russian and Arabic Languages and its Role in Achieving Translation Equivalence

open access: yesRUDN Journal of Language Studies, Semiotics and Semantics, 2021
The article is devoted to the issue of word-formation motivation, which does not lose its relevance and plays a role not only in disclosing formal-semantic relations between words of one language and has not only theoretical, but also applied ...

Reasoning about “reasoning about reasoning”: semantics and contextual equivalence for probabilistic programs with nested queries and recursion

open access: yesProc. ACM Program. Lang., 2022
Metareasoning can be achieved in probabilistic programming languages (PPLs) using agent models that recursively nest inference queries inside inference queries.
