ON AN ALGORITHMIC MODEL OF RELATIVITY.
UDC 519.7 Annotation: In the article the task of authentication of parameter is examined as a continuous function of parabolic equalization is in partials. Analytical expression is found for the calculation of gradient of the non–obvious set functional. Gradient is used to determine the modernized classical method of Lagrange multipliers. Keywords: finite state automata, interacting of automata, relativity.

USING GENERATIVE ADVERSARIAL NET FOR IDENTIFICATION EXAMINATION TASK.
UDC 004.93'1; 004.032.26 Annotation: This article is the first theoretical part of the work. The classification model based on the generative-adversarial net (GAN) is created for the identification examination task. The formalization of the identification examination task is performed in the form of a classification problem with a negative class. The overview of GAN is made. The improved techniques for semi-supervised learning GAN is described for classification tasks. Keywords: classification, semi-supervised learning, generative-adversarial net, neural network, identification
examination.

GROUP ANALYSIS AND ERGODICITY OF STOCHASTIC PROCESSES.
UDC 519.21 Annotation: In the paper the application of group analysis methods for stochastic differential Ito equations is considered. It is shown that the methods of group analysis of stochastic differential Ito equations make it possible to construct invariant probability measures of processes that do not have stationary distributions. Or lead to such for that one an invariant measure exists for it. Keywords: stochastic process, group analysis, symmetry, invariant measure.

GEOMETRICAL MODEL OF DEPENDENCE THE PHYSICAL PARAMETERS OF THE REFRIGERANT R407C.
UDC 004.942; 519.652 Annotation: The paper presents and analytically describes a geometric model the physical state of the refrigerant R407C. This model is the dependence of enthalpy on temperature and volume of a substance. The developed geometric model is presented in the form of a two-parameter response surface, which belongs to three-dimensional space. This model is described using the mathematical apparatus of geometric modeling of processes and phenomena – BN-calculation. The analysis of effectiveness the geometric modeling of dependence the parameters enthalpy is presented: some enthalpy parameters were obtained as a result of graphical measurements using the log P-h thermodynamic diagram, other parameters were calculated on the basis of the developed geometric model. As a result, we can conclude that the geometric model is in good convergence with the log P-h thermodynamic diagram. Keywords: BN-calculation, geometrical model, surface compartment, support contours, forming surfaces,
refrigerant parameters.
