Summary: Members of the research team identify certain technical problems and make suitable mathematical models. Mathematical modelling and solving such problems give mathematicians in their field possibility for new contributions to existing theory and improvement of the known methods by new elements. In addition, collaborators from electrical engineering and computer sciences have new opportunities to solve and anallyse the technical problems.

Keywords: nonlinear least squares problem, parameter identification problem, parameter estimation, moving least squares, growth models, system of nonlinear equations, nets, seminets, partitions of a finite set

Research goals: Interdisciplinary co-operative team consisted of mathematicians and electrical engineers can define the mathematical models of problems in the field of electrical engineering. The results of research contribute to creation new understandings both in mathematics and electrical engineering. Mathematical methods for solving such problems are generally known, but they can be specially investigated in some cases important for the application. In these particular cases it is possible to obtain such results which general theory does not ensure. For the problems of the nonlinear extreme and specially for nonlinear least squares problems, one can examine conditions, prove existence theorems and modify well known methods or define new methods for solving these problems in more efficient way. Sparse, large scale nonlinear systems of equations with special matrix structure often appear in the applications of electrical engineering. Greater successfulness and efficiency of the applications can be achieved by means of using modified methods of quasi-Newton types in that kind of problems.
