Content

Algorithm engineering is a discipline between algorithm theory and computing practice. Theoretical algorithmics supplies us with a rich set of algorithms and data structures that, in principle, enable us to solve complex and hard real-world problems. Often the algorithms are
designed having the classical random-access machine in mind and the resource requirements of the developed algorithms are analysed in the worst-case or average-case scenario.

In algorithm engineering we design and analyse algorithms for more realistic machine models that take into account the existence of branch predictors, caches, disks, multi-cores, and clusters. In our analysis we take into account the constant factors in the leading terms of the resource bounds. We treat programs as first-class citizens and investigate how algorithms can be turned into reliable and efficient implementations and how these programs can be packaged into easy-to-use software libraries. We do experiments with real-world data and investigate how to solve typical problem instances efficiently.

To summarize, algorithm engineering can be seen as a general methodology for algorithmics. Its heart is an interwoven cycle of design, analysis, implementation, and experimentation. We will design algorithms and prove theorems about them, we will implement our algorithms and do experiments with the implementations. We will learn best practices of experimentation and library design.

- design algorithms and data structures for different models of computation
- describe algorithms using pseudo-code
- analyse the key performance characteristics of algorithms and data structures
- implement algorithms efficiently using a concrete programming language

Teaching and learning methods
- lectures
- seminar presentations
- assignments
- project
- project workshop
- written test
Formal requirements
- B.Sc.-level course on algorithms and data structures
- B.Sc.-level course on programming
- This course (AE) replaces the course Data Structures: Theory and Practice (DS:TP) in our M.Sc. programme so a student who has previously passed DS:TP cannot take AE.
- Additionally, AE replaces DS:TP in the specialization profile Algorithms and Data Structures
Academic qualifications
The course requires a solid foundation in algorithmics. Since there will be hands-on programming exercises, experience in one or more imperative programming languages (preferably C++) is necessary.

Exam
Credit7,5 ECTS
Type of assessment
Continuous assessment, 9 weeks
The exam consists of 4 elements:
- Written test (4 hours) in the second examination week
- Active participation and presentation
- 4 assignments
- 3-weeks project that results in a project workshop (4 hours) in the first examination week

In the final grade the weight of the different criteria is as follows: Assignments 25%, participation and presentations 20%, project 25%, and final 4-hours written test 30%.
AidAll aids allowed
Marking scale7-point grading scale
Censorship formNo external censorship
Several internal examiners
Re-examGrading is based on the same evaluation criteria as the ordinary exam; selected course elements can be reused or remade completely.
