Course description and aims

This course gives an overview of numerical methods for mathematical optimization problems and introduces some applications of optimization to solve problems arising from engineering. The numerical methods covered in this course include primal-dual interior-point method for linear programming problems, and various methods for nonlinear optimization problems and constrained optimization problems. The topic also includes combinatorial optimization and its numerical methods. As the applications to engineering, the course introduces mechanical measurements and optimization methods that imitate nature.

The rapid developments of computers have brought significant changes to mathematical methodology. To use this progress, new mathematical computing technology has increased in importance. One of such mathematical technology is numerical methods for mathematical optimization problems. This course introduces various mathematical methods. The knowledge of multiple methods will be an advantage to tackle practical problems. In addition, the introduction of applications in engineering will give a chance to understand the rapid developments of computers and optimization methods more deeply.
