The paper promotes a relatively novel class of multi-agent control systems named "impulsive" continuity equations. systems of this sort, describing the dynamics of probabilistically distributed "crowd" of homotypic individuals, are intensively studied in the case when the driving vector field is bounded and sufficiently regular. We, instead, consider the case when the vector field is unbounded, namely, affine in a control parameter, which is only integrally constrained. This means that the "crowd" can be influenced by "shock" impacts, i.e., actions of small duration but very high intensity. For such control continuity equations, we design an impulsive relaxation by closing the set of solutions in a suitable coarse topology. The main result presents a constructive form of the relaxed system. A connection of the obtained results to problems of contact dynamics is also discussed along with applications to optimal ensemble control and other promising issues. © Springer Nature Switzerland AG 2019.

This paper deals with the problem of optimal packing a given number of equal spheres into different closed sets. We consider the problem both in three-dimensional Euclidean and non-Euclidean spaces. The special algorithm based on optical-geometric approach is suggested and implemented. This approach is previously used only for packing circles in two-dimensional space. Numerical results are presented and discussed. © 2018

This paper reviews application of modern optimization methods for functionals describing Digital Pre-distortion (DPD) of signals with orthogonal frequency division multiplexing (OFDM) modulation. The considered family of model functionals is determined by the class of cascade Wiener–Hammerstein models, which can be represented as a computational graph consisting of various nonlinear blocks. To assess optimization methods with the best convergence depth and rate as a properties of this models family, we multilaterally consider modern techniques used in optimizing neural networks and numerous numerical methods used to optimize non-convex multimodal functions. The research emphasizes the most effective of the considered techniques and describes several useful observations about the model properties and optimization methods behavior. © 2021, Springer Nature Switzerland AG.

Spreadsheets are an important source of information and can be used to create domain models and knowledge bases. We implement an approach for transforming spreadsheets into domain models. This approach consists of 4 steps and based on the use of: an intermediate unified representation of spreadsheets in a canonicalized form, an original technique and software. A canonicalized form provides processing spreadsheets with arbitrary layouts and styles. The original technique provides a two-stage transformation: source spreadsheets to canonicalized tables and canonicalized tables to domain model fragments. Original software is presented by two tools: TabbyXL as a table transformation tool and Personal Knowledge Base Designer as a knowledge base prototyping tool. We present an experimental evaluation of the proposed approach for generating domain models. Two datasets are used for our experiment: Troy200 and ISI-161. We obtained high values of recall and precision (more than 90%) for both datasets. At the same time, the content of resulted domain model fragments was evaluated for the ISI161 dataset. This evaluation showed that 24% of concepts of the domain model for industrial safety inspection tasks were generated automatically by using our approach.

A distributed computing environment is being formed within the geoportal IDSTU sb ras, which is mainly used for processing spatial data. Processing services that implement the WPS standard, and data storage services, a catalog of WPS services, and service execution systems and their compositions have been developed. In the system for executing services statistics data is collected on user-made service calls. The analysis of the obtained statistical data is carried out in order to identify the data transfer between services calls and build service compositions.

1st International Workshop on Information, Computation, and control systems for Distributed Environments, ICCS-DE 2019

作者： Sidorov, I.A. Sidorova, T.V. Kurzibova, Ya.V. Matrosov Institute for System Dynamics and Control Theory of SB RAS Lermontov St. 134 Irkutsk664033 Russia Limnological Institute of SB RAS Ulan-Batorskaya St. 3 Irkutsk664033 Russia Irkutsk State University Karl Marks St. 1 Irkutsk664003 Russia

The high-performance computing systems include a large number of hardware and software components that can cause failures. Nowadays, the well-known approaches to monitoring and ensuring the fault tolerance of the high-performance computing systems do not allow to fully implement its integrated solution. The aim of this paper is to develop methods and tools for identifying abnormal situations during large-scale computational experiments in high-performance computing environments, localizing these malfunctions, automatically troubleshooting if this is possible, and automatically reconfiguring the computing environment otherwise. The proposed approach is based on the idea of integrating monitoring systems, used in different nodes of the environment, into a unified meta-monitoring system. The use of the proposed approach minimizes the time to perform diagnostics and troubleshooting through the use of parallel operations. It also improves the resiliency of the computing environment processes by preventive measures to diagnose and troubleshoot of failures. These advantages lead to increasing the reliability and efficiency of the environment functioning. The novelty of the proposed approach is underlined by the following elements: mechanisms of the decentralized collection, storage, and processing of monitoring data;a new technique of decision-making in reconfiguring the environment;the supporting the provision of fault tolerance and reliability not only for software and hardware, but also for environment management systems.

Combined non-convex optimization algorithms based on differential evolution, harmony search, firefly, and L-BFGS methods

引用

IOP Conference Series: Materials Science and Engineering 2021年第1期1047卷

作者： P Sorokovikov A Gornov Matrosov Institute for System Dynamics and Control Theory of SB RAS 134 Lermontov Street Irkutsk 664033 Russian Federation

The paper presents an approach to the numerical investigation of the problems of finding a global optimum of multiextremal functions, based on the use of bioinspired and local search methods. Three combined non-convex optimization algorithms are proposed and implemented. As globalized bioinspired methods, differential evolution, harmony search, and firefly methods are used. For local descents, we used the L-BFGS method. The numerical study of modifications of the implemented approach has been carried out using known non-convex test functions. The developed algorithms have been applied to investigate the problem of the optimal orientation of the aircraft in space. The obtained numerical results allowed us to demonstrate the efficiency of the proposed algorithms.

IOP Conference Series: Earth and Environmental Science 2021年第1期629卷

作者： I V Bychkov G M Ruzhnikov R K Fedorov A E Khmelnov A K Popova Institute for System Dynamics and Control Theory SB RAS Irkutsk Russia

The Baikal Natural Territory includes Lake Baikal, its water protection zone, the basin within the territory of the Russian Federation, adjacent specially protected natural areas, and also the territory adjacent to the lake up to 200 kilometers wide to the west and northwest of it. The development of decisions to solve environmental problems of Baikal Natural Territory should be based on a comprehensive analysis of the monitoring data. The monitoring data and analysis methods are distributed among participants (organizations and departments). But data and analysis methods exchange is very low. An approach is proposed for the introduction of digitalization in the environmental monitoring of the Baikal natural territory, based on the integrated implementation of cyber-physical systems, the digital method of data transmission, as well as the use of digital ecosystems and platforms using the service-oriented paradigm, OGC standards, end-to-end and WEB technologies, cloud and distributed computing, large amounts of spatio-temporal data. Based on service-oriented paradigm digital resources and processing services implementing REST or WPS standard should be created by the monitoring participants. Requirements for digital resources have been defined. Infrastructure components have been developed to simplify development of digital resources, processing services and to organize interaction among participants.
