In this paper we observe the opportunity to offer new methods of solving NP-hard problems which frequently arise in the domain of information management, including design of database structures and big data processing. In our research we are focusing on the Maximum Clique Problem (MCP) and propose a new approach to solving that problem. The approach combines the artificial neuro-network paradigm and genetic programming. For boosting the convergence of the Hopfield Neural Network (HNN) we propose the genetic algorithm as the selection mechanism for terms of energy function. As a result, we demonstrate the proposed approach on experimental graphs and formulate two hypotheses for further research.
The paper discusses a multi-paradigm approach to the modeling of Demand Responsive Transport systems. It contains a brief overview of issues which appear during modeling of such systems, considers various multi-agent architectures and describes some algorithms which can be used for modeling. Also the paper provides some details about previous investigations on this topic, in particular: a centralized model based on combinatorial auctions and a multi-agent based multi-layer distributed hybrid model. The aim of the paper is working out a sound solution based on a combination of these two approaches which would utilize “system of systems” engineering approach where layered architecture would help to deal with real-time issues and increase system’s reliability and combinatorial auctions would help with global search of the optimal solution. Such combination improves the efficiency and reliability of the system.
In this paper, we provide the solution for RecSys Challenge 2018 by our Avito team, which obtained the 3rd place in main track. The goal of the competition was to recommend music tracks for automatic playlist continuation. As a part of this challenge, Spotify released a large public dataset, which allowed us to train a rather complex algorithm. Our approach consists of two stages: collaborative filtering for candidate selection and gradient boosting for final prediction. The combination of these two models performed well with the playlist and track metadata given.
In 1937, the Japanese economist Kaname Akamatsu discovered specific links between the rise and decline of the global peripheries. Akamatsu’s theory of development describes certain mechanisms whose working results in the narrowing of the gap between the level of development of the economy of developing and developed countries, and, thus, in the re-structuring of the relationships between the global core and the global periphery. Akamatsu developed his model on the basis of his analysis of the economic development of Japan before World War II, with a special emphasis on the development of the Japanese textile industry. Akamatsu’s catch-up development includes three phases: import of goods, organization of the production of previously imported products, and export of those goods. This model proved to be productive for analyzing the development of many other developing countries, especially in East Asia, making the theory of flying geese popular among the economists of these countries, as well as the whole world. The “flying geese” model produces certain swings that may be denoted as Akamatsu waves. Akamatsu waves may be defined as cycles (with a period ranging from 20 to 60 years) that are connected with convergence and divergence of core and periphery of the World System in a way that explains cyclical upward and downward swings (at global and national levels) in the movements of the periphery countries as they catch up with the richer ones.

We propose a new algorithm for consensus clustering, FCA-Consensus, based on Formal Concept Analysis. As the input, the algorithm takes T partitions of a certain set of objects obtained by k-means algorithm after T runs from different initialisations. The resulting consensus partition is extracted from an antichain of the concept lattice built on a formal context objects×classes, where the classes are the set of all cluster labels from each initial k-means partition. We compare the results of the proposed algorithm in terms of ARI measure with the state-of-the-art algorithms on synthetic datasets. Under certain conditions, the best ARI values are demonstrated by FCA-Consensus.
On the eve of the great troubles: Th e letter sent to the king Henry the Second by the bishop of Nevers
One of the important sources, introducing in many aspects the Civil wars of the 16th century, is the treatise written at the beginning of 1559 and stored in the Paris library of Sainte Genevieve, the “Letter, sent to king Henry the second by Bishop of Nevers. A message from may, 1559”. Its author, with very high probability, was Jacques the Bishop of Nevers Spifame and the text was written in spring of 1559 after his escape from France.
This article is to analyze this little-known source-text. In an address to the monarch the author announces his intention to give advice, how to distinguish the false Church from the true, to explain why and how exactly to cut back on numerous Church benefi ces for the common good, and fi nally to show the path to the cessation of troubles. Despite the subsequent and scandalous fame of Jacques Spifame, the letter was not widely known and was not published. Th is is not surprising, because it very quickly became irrelevant due to the death of the addressee, the French king Henry II.

A.Herzen as a scholar of contemporary history: Polish aspects. Herzen considered the Polish national movement as the main ally of Russian revolutionaries in their struggle against autocracy and highly appreciated the Poles' sacrifice. However the moderate nature of Polish social doctrine and demands to restore the former eastern border of the Polish-Lithuanian Commonwealth caused Herzen's critical evaluations. The Polish partners of Herzen were not ready to share all of his ideas. Differences of the programs complicated Russian-Polish revolutionary cooperation. Analyzing the Russian-Polish relations of the last three decades, Herzen proposed his own vision of the Russian Empire's contemporary history.
The idea of the high significance of Platonic studies for our comprehension many phenomena in politics, ideology and philosophy of the twentieth century and of our days is all played out. The social project of Plato was considered to be the paradigmatic model for totalitarian regimes of Nazi Germany and Bolshevik Russia or—recently—the only basis for the solution of all contemporary global problems. In this paper some of the main aspects of the analysis of “the social nature of Platonism” by the Russian philosopher and historian of philosophy Aleksey F. Losev (1893–1988) were discussed — predominately as this analysis is given in the outline of the same name, Social Nature of Platonism, included in The Outlines of Antique Symbolism and Mythology (1930).
The paper examines the history of dissemination in 14th-17th centuries in different european countries (especially in Eastern Europe), of one curious text, known as the "Privilege of Alexander the Great for the Slavs." Particular attention was given to the specifically Russian version of this text appeared in the latter half of the XVI century.
The early decades of the nineteenth century were a period of “proactive” improvement and “balance of the imperial situation,”1 both in the content of administrative projects and in their implementation in practices of territorial administration in the Russian Empire. However, Alexander I’s attempt at reforming local administration in 1816–25 remains understudied. The emperor, known for his cautiousness and indecision, endorsed the ideas of Aleksandr Dmitrievich Balashov2 and Viktor Pavlovich Kochubei,3 who called for introduction of viceroyalties (namestnichestvo) as administrative units in the empire. It is still unknown whether Nikolai Nikolaevich Novosil’cev or A.D. Balashov was the true author of the project,4, but without the political will of the monarch, implementation would have been impossible. The empire was to be structured in accordance with a document titled “The List of Governorates and Their Distribution across Viceregal Regions” (Spisok gubernii s raspredeleniem po namestnicheskim okrugam). Amended in 1823–24, it was included in the Book of Civil Statutes (Kniga shtatov po grazhdanskoi chasti)5 and preserved in the archives of the secret “Committee on December 6, 1826.” At the end of the nineteenth century, this list of governor-generalships—as found in the committee papers—was published in the Sbornik Rossiiskogo Imperatorskogo Obshchestva, with further amendments simply ignored.6 This version of the text is most referenced by scholars.
The paper considers Egyptian and Classical connotations for the epithet of Alexander the Great "the new Sesonchosis" in a passage of the Alexander Romance describing his advent to Egypt
The chapter juxtaposes Veselovsky’s theory of the persistence of forms with the set of critical practices known as New Historicism, and shows that both approaches exclude the possibility of new forms arising. The chapter suggests that both the oblivion of an old form and the rise of the new result from a fundamental shift in perception that occurs within the order of verbal creativity and does not lend itself to a historical-deterministic explanation.
