Multi-choice has become a significant part of the real-life decision-making process. Most
of the problems involve more than one parameter as a choice, and among those different
choices only one choice is to be made, which will optimize the objective function. The
difficulty in making such a choice can be at ease with the help of mathematical techniques.
In this paper, we propose a novel solution procedure to handle the multi-choice parameters
in the constraint using cubic spline interpolation method. After analyzing the results, we
observed that the proposed method yields better results as compared to existing methods.
Two numerical examples are presented to explain the method and validate the fact of complete
utilization of the resources

The book focuses on the concept of “socialist market, a cornerstone of political economy in Soviet-type societies undergoing economic reforms from the 1950s onward. Encouraged by the success of non-capitalist mixed economies, market reformers (also called 'market socialists') offered the communist ruling elites a remedy for the persistent crises of the planned economy. Besides optimal planning and ...

By the Ramsey number R(K1,s,Pt) one means the least positive integer n such that, for every n-vertex graph G, the following condition holds: either G contains a vertex of degree at least s or the complement of G contains a simple t-path. In this paper, we fi nd precise values of R(K1,s,Pt) for certain values ...

A convenient approach to optimally solving combinatorial optimization tasks is the Branch-and-Bound method.
Its branching heuristic can be learned to solve a large set of similar tasks. The promising results here are
achieved by the recently appeared on-policy reinforcement learning method based on the tree Markov Decision
Process. To overcome its main disadvantages, namely, very large training time ...

Distilled fermented milk beverages are rare in food technology, despite the global prevalence of plant-based spirits. Currently, the production of distilled strong alcoholic beverages from fermented milk using traditional technologies is known only among Mongolic-speaking peoples and their Siberian neighbors. This study provides the first interdisciplinary analysis of darasun, a traditional Buryat spirit made from fermented ...

This paper presents a review of artificial intelligence (AI) methods for failure prediction in data center cooling systems, with a focus on the integration of digital twins (DTs), physics-informed learning, and graph-based models. Positioned within complex network science, this review addresses a limitation of conventional graph approaches—their reliance on pairwise connectivity—whereas real-world failures often arise ...

The article examines Trump’s tariff policy, proclaimed at the beginning of his second presidential term and its negative impact on the stability of the global economy. It is emphasized that the practice of manipulating import duties used by the Trump administration fundamentally contradicts the basic ideas on which the Multilateral trading system has been built since the early 1940s, in particular, predictability of mutual ...

Scientific collaboration among universities is traditionally studied by counting coauthored papers with different types of partners. Under this approach, the internal mechanisms of collaboration remain hidden and, without additional normalization, the results can be biased. In our study, we apply co-authorship network analysis to examine collaboration structures within university research networks. We use OpenAlex data ...

A reliable evaluation of the population's socioeconomic behavior must consider "overlapping activities," which is reflected in combining leisure with other tasks. Based on data from the HSE Economic Behavior of Households research project, the paper examines patterns of overlapping leisure consumption in contemporary Russian society. The authors evaluated the frequency and amount of overlapping leisure ...

This article investigates the problem of approximating the generalized
Erdélyi-Kober fractional operator (often referred to as the Lowndes operator)
using cubic splines. A method based on cubic spline interpolation
is proposed for approximating the operator on a non-uniform grid. The
convergence rate of the proposed method is proven, and its stability is
analyzed. Error bounds are established for functions in ...

discipline of their numbering by unitary addition of certain elements ...

Topic modelling is an area of text mining that has been actively developed in the last 15 years. A probabilistic topic model extracts a set of hidden topics from a collection of text documents. It defines each topic by a probability distribution over words and describes each document with a probability distribution over topics. In ...

We present a probabilistic model with discrete latent variables that control the computation time in deep learning models such as ResNets and LSTMs. A prior on the latent variables expresses the preference for faster computation. The amount of computation for an input is determined via amortized maximum a posteriori (MAP) inference. MAP inference is performed ...

The paper considers the task of the morphemic analysis of Russian words and compares the efficiency of several proposed models. These models can be divided into three groups: derivational and inflectional rule-based, proba- bilistic, and hybrid models. The latter achieved state-of-the-art results of 0.848 F-score on a test set of 500 Russian words. The models ...

Objective. Brain-computer interface (BCI) systems are known to be vulnerable to variabilities in background states of a user. Usually, no detailed information on these states is available even during the training stage. Thus there is a need in a method which is capable of taking background states into account in an unsupervised way. Approach. We ...
