The review examines how TikTok's algorithms and users shape media social representations. Algorithms act as subjects of communication, selecting content for user interpretation, while media and users have to adapt. The platform balances algorithm-centric and audience-centric approaches to representation formation. ...

The paper proposes a system of definitions for the basic concepts of computability theory that underlie the mathematics of the digital world: algorithm, computability, calculus, object complexity, close to modern undertnding. Hierarchies of the finite and the problem of consistency are considered. ...

The paper studies the association between the artificial intelligence (AI) and employment characteristics. As a theoretical framework, we use the Acemoglu et al. model, which introduces opposing effects of the AI algorithms on labor employment on the firm level such as substitution effect and complimentary/ productivity effects. Depending on their relative strength, the AI algorithms ...

Clustering has always been in great demand by scientific and industrial communities. However, due to the lack of ground truth, interpreting its obtained results can be debatable. The current research provides an empirical benchmark on the efficiency of three popular and one recently proposed crisp clustering methods. To this end, we extensively analyzed these (four) ...

This article is a review of Pippin Barr’s book The Stuff Games Are Made Of (2023), which explores various elements of game worlds. Over the course of ten chapters, including introduction and conclusion, the author of the monograph examine samples with stable basic concepts of computer games and their production. Being a game designer and a theorist, Pippin Barr reflects on many ‘medianized’ ...

For given edge-capacitated connected graph and two its vertices s and t, the bottleneck (or max min ) path problem is to find the maximum value of path-minimum edge capacities among all paths, connecting s and t. It can be generalized by finding the bottleneck values between s and all possible t. These problems arise ...

For a given graph, the edge-coloring problem is to minimize the number of colors sufficient to color all the graph edges so that any adjacent edges receive different colors. For all classes defined by sets of forbidden subgraphs, each with 7 edges, the complexity status of this problem is known. In this paper, we obtain ...

The issue of the protection of legitimate rights of personas who were defamed is not new in Russian legal science. The problem of protection of honor and dignity was known to classical Roman law, was the subject of study of pre-revolutionary and Soviet lawyers. However, the classic civilistic constructions formulated in the Civil Code were ...

The problem of query answering over incomplete attributed graph data is a challenging field of database management systems and artificial intelligence. When there are rules on data structure expressed in the form of the ontology, the theoretical complexity of finding exact solution satisfying ontology constraints increases. Logic-based methods use theoretical constructions to obtain efficient rewritings ...

The novel methods for binary discrete Fourier transform (DFT) computation over the finite field have been proposed. The methods are based on a binary trace calculation over the finite field and use the cyclotomic DFT. The direct DFT computational complexity has been reduced due to using the binary trace function over the finite field and ...

Complexity function and complexity of validity of modal and superintuitionistic propositional logics
Rybakov M., Shkatov D., Journal of Logic and Computation 2023 Vol. 33 No. 7 P. 1566–1595
We consider the relationship between the algorithmic properties of the validity problem for a modal or superintuitionistic propositional logic and the size of the smallest Kripke countermodels for non-theorems of the logic. We establish the existence, for every degree of unsolvability, of a propositional logic whose validity problem belongs to the degree and whose every ...

A hereditary class is a set of simple graphs closed under deletion of vertices; every such class is defined by the set of its minimal forbidden induced subgraphs. If this set is finite, then the class is said to be finitely defined. The concept of a boundary class is a useful tool for the analysis ...

Abstract: The computational complexity of the element (Formula presented.) of the Abelian group (Formula presented.) (it is supposed that kii for all i) and the computational complexity of the term (Formula presented.) are compared in the paper. The computational complexity means the minimal possible number of multiplication operations, and all the results of intermediate multiplications ...

Accurate simulation of complex biological processes is an essential component of developing and validating new technologies and inference approaches. As an effort to help contain the COVID-19 pandemic, large numbers of SARS-CoV-2 genomes have been sequenced from most regions in the world. More than 5.5 million viral sequences are publicly available as of November 2021. ...

We prove that branching-time temporal logics CTL and CTL* are polynomial-time embeddable into their single-variable fragments. It follows that satisfiability for CTL and CTL*, and therefore also for alternating-time temporal logics ATL and ATL*, in languages with one propositional variable is as algorithmically hard as satisfiability for the full logic: EXPTIME-complete for CTL and ATL, and 2EXPTIME-complete for CTL* and ATL*. We discuss applicability of the technique used in the proofs to other ...

The vertex 3-colourability problem is to decide whether the vertex set of a given graph
can be split into three subsets of pairwise non-adjacent vertices. This problem is known
to be NP-complete in a certain class of graphs, defined by an explicit description of
allowed 5-vertex induced subgraphs in them. In the present paper, we improve this
result by ...

We consider a computational model which is known as set automata. The set automata are one-way finite automata with additional storage-the set. There are two kinds of set automata-deterministic (DSA's) and nondeterministic (NSA's). The model was introduced by Kutrib, Malcher, Wendlandt in 2014. It was shown that DSA-recognizable languages look similar to DCFL's and NSA-recognizable ...

Traditionally, description logic has focused on represent- ing and reasoning about classes rather than relations (roles), which has been justified by the deterioration of the computa- tional properties if expressive role inclusions are added. The situation is even worse in the temporalised setting, where monodicity is viewed as an almost necessary condition for decidability. We ...
