Content, Learning Outcome and Preconditions

Content

Discrete Fourier transform and related transforms
- FFT: derivation and implementation
- Fast discrete cosine/sine transforms: derivation and implementation via FFT
- Applications: multi-dimensional data (images, video, audio) and FFT-based solvers for linear systems of equations

Space-filling curves
- Peano- and Hilbert curves: representation by algebraic and grammatical means
- Applications: organisation of multi-dimensional data; parallel, adaptive, and cache oblivious algorithms

Hierarchical numerical methods
- Hierarchical bases for one- and multi-dimensional problems
- Computational cost versus accuracy; Sparse Grids
- Adaptive representation of continuous data
- Applications: numerical quadrature, differential equations
- Outlook: multigrid methods, wavelets

Learning Outcome

At the end of the module, students are able to identify, explain, and implement selected hierarchical methods that are of particular interest to the informatical aspects of scientific computing because of their algorithmic structure and their significance for practical applications.
Participants can analyse and judge the efficiency of such methods by deriving statements about the required computational cost and - where applicable - the achieved accuracy and by comparing them with corresponding results for other methods.
The students are able to transfer the methodology to new methods for related problems.

Learning and Teaching Methods

This module comprises lectures and accompanying tutorials. The contents of the lectures will be taught by talks and presentations.
Students will be encouraged to study literature and to get involved with the topics in depth. In the tutorials, concrete problems will be solved - partially in teamwork - and selected examples will be discussed.

Module Exam

Description of exams and course work

Type of Assessment: The exam takes the form of a 120 minutes written exam.
The examination consists of a written exam of 120 minutes in which students show that they are able to find solutions for algorithmic problems arising in the field of scientific computing in a limited time. Questions and small tasks concerning code are used to test the student´s knowledge on known and related hierarchical methods as well as their ability to implement them. Example algorithms and questions are used to examine the capability of analyzing the efficiency of algorithms and the accuracy of a given method.

Exam Repetition

The exam may be repeated at the end of the semester.
