INTENDED LEARNING OUTCOME

At the end of the course, the students will have an understanding of modern algorithms in nonlinear optimization. They will know their applications from several fields and they will understand which method is suitable for which application.


CONTENT

The course consists of two parts. The first one provides an overview of modern optimization methods while the second one shows selected applications. The first part will be theoretical and the emphasis will be given on explaining how different optimization approaches work. Their strengths and weaknesses will be properly analyzed. The second part will use this knowledge and show how these methods can be applied to modern machine learning applications or topology optimization.
