Studies in Computational Intelligence 961 Ivan Georgiev Hristo Kostadinov Elena Lilkova Editors Advanced Computing in Industrial Mathematics 13th Annual Meeting of the Bulgarian Section of SIAM, December 18–20, 2018, Sofia, Bulgaria, Revised Selected Papers Studies in Computational Intelligence Volume 961 Series Editor Janusz Kacprzyk, Polish Academy of Sciences, Warsaw, Poland The series “Studies in Computational Intelligence” (SCI) publishes new develop- mentsandadvancesinthevariousareasofcomputationalintelligence—quicklyand with a high quality. The intent is to cover the theory, applications, and design methods of computational intelligence, as embedded in the fields of engineering, computer science, physics and life sciences, as well as the methodologies behind them. The series contains monographs, lecture notes and edited volumes in computational intelligence spanning the areas of neural networks, connectionist systems, genetic algorithms, evolutionary computation, artificial intelligence, cellular automata, self-organizing systems, soft computing, fuzzy systems, and hybrid intelligent systems. Of particular value to both the contributors and the readership are the short publication timeframe and the world-wide distribution, which enable both wide and rapid dissemination of research output. Indexed by SCOPUS, DBLP, WTI Frankfurt eG, zbMATH, SCImago. All books published in the series are submitted for consideration in Web of Science.

The sectionwasformedin2007withthepurposetopromoteandsupporttheapplication of mathematics to science, engineering, and technology in Bulgaria. ThegoalsofBGSIAMfollowandcreativelydevelopthegeneralgoalsofSIAM as follows: (cid:129) To advance the application of mathematics and computational science to engineering, industry, science, and society; (cid:129) To promote research that will lead to effective new mathematical and compu- tationalmethodsandtechniquesforscience,engineering,industry,andsociety; (cid:129) To provide media for the exchange of information and ideas among mathe- maticians, engineers, and scientists. DuringtheBGSIAM’18conference,awiderangeofproblemsconcerningrecent achievementsinthefieldofindustrialandappliedmathematicswerepresentedand discussed.Themeetingprovidedaforumforexchangeofideasbetweenscientists, whodevelopandstudymathematicalmethodsandalgorithms,andresearchers,who apply them for solving real-life problems. Among the topics of interest are mathematical physics, numerical analysis, high-performance computing, optimization and control, mathematical biology stochastic modeling, machine learning, digitization and imaging, big data, and advanced computing in environmental, biomedical, and engineering applications.
