the article analyzes the economic instruments used by states in domestic and foreign policy from the point of view of identifying the existing coercive mechanisms in modern social practices. The study revealed how states use economic instruments as the preferred means of geopolitical struggle. In addition, the work separately reflects the fact that States should preserve the right to an original socio-economic model of development. We should also not forget about the negative consequences of unilateral coercive measures. Using the method of cognitive modeling and constructing cognitive maps, the authors identify the connections in the analyzed social practices from the perspective of studying the means of geo-economic pressure.

The article deals with the difference model of coordination of general and private interests in the distribution of resources in marketing networks. The dynamics of a managed system describes the interaction of members of the target audience (base agents), leading to a change in their opinions (spending on the purchase of goods and services of firms competing in a certain market). The gain of each firm includes two components: the total opinion of the base agents, taking into account marketing costs (the common interest for all agents of influence) and the return on investment in some private activity. The Coordinating Center determines the marketing budgets of the firms and maximizes the total opinion of the base agents, taking into account the resources allocated to the firms. The total discounted income of the Center and the agents of influence are found. The results are analyzed and the optimal allocation of resources is concluded.

The model of passenger traffic movement was evaluated to identify hidden patterns in the processes of passenger traffic formation using standard electronic computers with general-purpose software. Several sessions of simulating the movement of passengers between stops of urban passenger public transport, belonging to different levels of attractiveness of stops for passengers, were conducted. The features of the quasi-deterministic movement of passengers between stops of urban passenger transport that are not included in the list of stops of mass attraction of passenger traffic, and points of mass attraction of passengers are considered. Examples of typical patterns in the choice of destination stops and in the hourly flow of passengers from departure stops are given. The comparison of the number of daily visits to stops of mass attraction of passenger traffic, obtained by processing the simulation results with the initial statistical data, is carried out.

This paper considers the vectorization and parallelization of the "particle-particle" method used to take into account interactions between objects in the mathematical modeling of physical processes, using the example of taking into account the space charge when calculating the dynamics of charged particles. Comparison and estimation of time costs are carried out (as a test problem, the expansion of a multicomponent ion beam during one nanosecond with a step of Δt = 10-12 s was considered), taking into account the acceleration due to vectorization and parallelization between processor cores. It is concluded that the results of the work clearly demonstrate that the vectorization of computations can significantly speed up the computation time, and the explicit replacement of scalar operations with vector ones makes it possible to obtain additional speed-up in comparison with the use of automatic optimization of the program code. Key words: parallel computations, "particle-particle" method, vectorization of computations, numerical modeling, Coulomb interactions, dynamics of charged particles, ion beam, program code, equation of motion, mathematical model.

A model of passenger traffic movement is proposed that is suitable for identifying hidden patterns in the processes of passenger flow creation. The passenger flow is divided into four components, for which separate passenger flow submodels are developed: quasi-deterministic passenger flow from leaving stops to points of mass attraction of passengers; stochastic hourly passenger flow from each arrival stop to different districts of the city; stochastic flow that models the distribution of passengers between final stops in accordance with the degree of popularity of stops; chaotic distribution of passenger traffic between stops with a small number of daily visits. The results of calculations of the quasi-deterministic passenger traffic submodel from leaving stops to points of mass passenger attraction are estimated.

the article describes a variant of setting sequential algorithms in the form of bipartite graphs by further defining them, which makes it possible to work with algorithms using graph theory methods in the future. Two forms of the task are considered: modular and functional-predicative. The possibility of setting the algorithm in table-predicate form is shown. It is concluded that in addition to the generally accepted methods of setting the algorithm, it can be set in matrix-predicate or table-predicate form, which allows using methods of matrix theory and methods of predicate theory when working with algorithms. setting the algorithm in matrix-predicate form avoids isomorphism when performing algebraic and set-theoretic operations on it.; setting algorithms in matrix-predicate form allows you to perform almost any operations on them

To date, the socio-economic situation in the country creates for the population quite significant obstacles in the implementation of tasks for the purchase of housing and other real estate through mortgage lending. However, when it comes to collecting the amounts owed on the loan, banks are faced with an analysis of the prospects for the sale of mortgaged property, as a result of which, in most cases, come to the conclusion that the original sale price of the mortgaged property with the realities of the market. In the article, the authors consider the judicial practice of determining the initial price of the mortgaged property and analyze the situation in which there is a need for judicial value examination, as well as give the main aspects of the methodology of this type of expertise. The purpose of the article is to form a clear idea of the reader about the process of resolving the dispute arising from the breach of obligations under the loan agreement.

The article shows the possibility of describing complex objects with parallel functioning components in the form of structures built on the basis of neural networks. The neural network is represented by an operator matrix, that is, a formal description that gives a universal way to solve many non-standard control problems.
