 1 Name of the discipline VARIATIONAL CALCULATION AND METHODS OF OPTIMIZATION 2 Study course, specialty 4, Mathematics and Information (Web Programming and Internet Technologies) 3 Semester of study 7 4 Amount of credits 3 5 Lecturer’s S.N.P. Lebedev Andrey Vladimirovich 6 Aims of the study The study of the basic methods for solving classical problems of finite-dimensional optimization. Increase the level of professional competence in solving optimization problems. Further development of students’ skills in abstract mathematical thinking and the ability to apply it in specific tasks, increase their mathematical culture. As a result of the study, the student should be able to: – find the minimum and maximum points for functions defined on finite-dimensional spaces; – construct models of extremal problems in finite-dimensional spaces; – with the aid of differential convexity criteria, to check whether a given function is convex; – use optimality conditions and the Kuhn-Tucker criterion for solving convex programming problems; – use the simplex method for solving linear programming problems; – use the optimality conditions of the first and second order to solve nonlinear programming problems. 7 Prerequisites Mathematical analysis Algebra and Number Theory Differential equations Optimization methods in finite-dimensional spaces Functional Analysis 8 Contents of the discipline Optimization problems in infinite-dimensional spaces.
