    Synthesis of the structure of organised systems as central problem of evolutionary cybernetics
    Computer Research and Modeling, 2023, v. 15, no. 5, pp. 1103-1124

    The article provides approaches to evolutionary modelling of synthesis of organised systems and analyses methodological problems of evolutionary computations of this kind. Based on the analysis of works on evolutionary cybernetics, evolutionary theory, systems theory and synergetics, we conclude that there are open problems in formalising the synthesis of organised systems and modelling their evolution. The article emphasises that the theoretical basis for the practice of evolutionary modelling is the principles of the modern synthetic theory of evolution. Our software project uses a virtual computing environment for machine synthesis of problem solving algorithms. In the process of modelling, we obtained the results on the basis of which we conclude that there are a number of conditions that fundamentally limit the applicability of genetic programming methods in the tasks of synthesis of functional structures. The main limitations are the need for the fitness function to track the step-by-step approach to the solution of the problem and the inapplicability of this approach to the problems of synthesis of hierarchically organised systems. We note that the results obtained in the practice of evolutionary modelling in general for the whole time of its existence, confirm the conclusion the possibilities of genetic programming are fundamentally limited in solving problems of synthesizing the structure of organized systems. As sources of fundamental difficulties for machine synthesis of system structures the article points out the absence of directions for gradient descent in structural synthesis and the absence of regularity of random appearance of new organised structures. The considered problems are relevant for the theory of biological evolution. The article substantiates the statement about the biological specificity of practically possible ways of synthesis of the structure of organised systems. As a theoretical interpretation of the discussed problem, we propose to consider the system-evolutionary concept of P.K.Anokhin. The process of synthesis of functional structures in this context is an adaptive response of organisms to external conditions based on their ability to integrative synthesis of memory, needs and information about current conditions. The results of actual studies are in favour of this interpretation. We note that the physical basis of biological integrativity may be related to the phenomena of non-locality and non-separability characteristic of quantum systems. The problems considered in this paper are closely related to the problem of creating strong artificial intelligence.

    A Monte-Carlo study of the inner tracking system main characteristics for multi purpose particle detector MPD
    Computer Research and Modeling, 2019, v. 11, no. 1, pp. 87-94

    At present, the accelerator complex NICA is being built at JINR (Dubna). It is intended for performing experiments to study interactions of relativistic nuclei and polarized particles (protons and deuterons). One of the experimental facilitues MPD (MultiPurpose Detector) was designed to investigate nucleus-nucleus, protonnucleus and proton-proton interactions. The existing plans of future MPD upgrade consider a possibility to install an inner tracker made of the new generation silicon pixel sensors. It is expected that such a detector will considerably enhance the research capability of the experiment both for nucleus-nucleus interactions (due to a high spatial resolution near the collision region) and proton-proton ones (due to a fast detector response).

    This paper presents main characteristics of such a tracker, obtained using a Monte-Carlo simulation of the detector for proton-proton collisions. In particular, the detector ability to reconstruct decay vertices of short-lived particles and perform a selection of rare events of such decays from much more frequent “common” interactions are evaluated. Also, the problem of a separation of multiple collisions during the high luminosity accelerator running and the task of detector triggering on rare events are addressed. The results obtained can be used to justify the necessity to build such a detector and to develop a high-level trigger system, possibly based on machine learning techniques.

    Computational task tracking complex in the scientific project informational support system
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 615-620

    This work describes the idea of the system of informational support for the scientific projects and the development of computational task tracking complex. Due to large requirements for computational experiments the problem of presentation of the information about HPC tasks becomes one of the most important. Nonstandard usage of the service desk system as a basis of the computational task tracking and support system can be the solution of this problem. Particular attention is paid to the analysis and the satisfaction of the conflicting requirements to the task tracking complex from the different user groups. Besides the web service kit used for the integration of the task tracking complex and the datacenter environment is considered. This service kit became the main interconnect between the parts of the scientific project support system and also this kit allows to reconfigure the whole system quickly and safely.
