The aim of this work is the implementation and comparison of genetic algorithms in the framework of the problem of reinforcement learning for the control of unstable systems. The unstable system will be the CartPole Open AI GYM object, which simulates the balancing of a rod hinged on a cart that moves left and right. The goal is to keep the pole in a vertical position for as long as possible. The control of this object is implemented using two learning methods: the neuroevolutionary algorithm (NEAT) and the multilayer perceptron using genetic algorithms (DEAP).

The article analyzes the utopian context in architectural activity. Concepts aimed at finding and organizing an "ideal world" remain an urgent topic and feature of architectural thinking. The creative genre of utopia undergoes the next stage of genesis in modern conditions, in which utopian ideas and concepts are accompanied by theoretical and practical methods of predicting possible results, which allows not only to overcome the principle of the initial impracticability of utopia, but also to propose possible strategies for their practical implementation. The utopian approach to displaying the features of the properties and states of an intricate architectural image is becoming an especially important and noticeable phenomenon in the context of the formation and development of a global information and communication society focused on the full use of a variety of innovative technologies.

The process of determining the most effective design solution from the point of view of metal consumption for the dome structure of the designed exhibition complex in Rostov-on-Don with a plan diameter of 100 m is considered. Three different dome design options are analyzed. Calculation models were created in the Lira-SAPR software package and calculations of various coating options were performed. The obtained results were compared in terms of rigidity and conclusions were drawn about the possibility and feasibility of using each of the considered design solutions. The most efficient design option in terms of metal consumption was selected.

The development of a decision support system for evaluating a fashionable image of a person is described. This is done by selecting a set of visual attributes from an image and comparing this set with "fashionable" patterns. Fashion patterns are set by the user himself. These are images that are defined in the system as reference images. This paper provides an overview of decision-making methods, analyzes the relevance of decision-making systems in different spheres of society. The algorithm of the program and the tools with which the image is first preprocessed are considered, then the visual attributes are highlighted. The method of making decisions for different types of attributes is given. The comparison of colors in HSL notation is considered.

The article discusses the developed model for recognizing a clothing brand by image. The model not only predicts the type and brand of clothing, but can also determine their similarity. At the initial stage, a dataset was collected containing images of clothing from various brands with a total volume of 9,000 images. In this work, the ViT (Vision Transformer) neural network architecture was used, a model for working with images, which was presented by experts from Google Brain. The vit-base-patch16-224 model acted as a representative of the transformer architecture. Before training, all images were converted to black and white, and data augmentation was also used: image rotation by a random angle, mirror transformation. All photos have been normalized – pixel coordinates have been adjusted to the interval [0,1].

In the context of the development of energy-efficient construction production, the issue of eliminating the irrational consumption of fuel and energy resources and regulating their consumption in the course of construction and installation work, including the demolition of an object, has been updated. The article discusses the features of the production of dismantling works in the process of renovation of residential buildings, taking into account the consumption of fuel and energy resources by the main consumers - means of mechanization. On the example of a five-story brick residential building, the total energy consumption during demolition by the method of mechanical collapse and element-by-element disassembly with the preservation of suitable materials was determined, and the relationship between these two options was established. The calculations showed that the consumption of fuel and energy resources during the element-by-element dismantling of all building structures with the preservation of suitable materials for brick heated buildings is 55.3% less compared to dismantling the building by the collapse method; in monetary terms, the energy costs for option 1 exceed the costs for option 2 by 1.55 times.

Products made of gypsum binders have heat and sound insulation properties, fire resistance, high technical, economic and environmental indicators, which are used in construction in the construction of internal walls and partitions, the total area of which, as a rule, is several times larger than the area of external walls. By reducing the density of gypsum products due to the introduction of light aggregates, it is possible to reduce the mass of walls, lighten the building, reduce the load on foundations and reduce the cost of construction, while improving thermal protection. However, traditional lightweight fillers increase the water demand of the mixture and reduce the strength of the material. Therefore, in the article, the purpose of the study was to determine the optimal composition of gypsum compositions with various types of filler to obtain the best set of properties of the obtained samples.

The technical solution for the construction of local treatment of return drainage flow from an irrigated area, based on the use of ion-exchange filter materials, is proposed. It has been established that the concentration of chemicals in the water of the drainage well is 1/3 lower than in the open collector, where the drainage flow is diverted. Therefore, the localization of the technological unit for the treatment of drainage water relative to the drainage well is a reasonable decision, since it will reduce the financial costs of filter media and the frequency of their replacement. The technological scheme of the treatment plant based on the block principle is described: by disconnecting or connecting individual blocks, it is possible to respond flexibly to changing needs in the quality and degree of drainage water treatment.
