Course introduction
The field of approximation algorithms has developed in response to the difficulty in solving important optimization problems to optimality.  In contrast to heuristics, approximation algorithms come with a guaranteed running time and solution quality.  As a simple example, consider the greedy algorithm which gives a vertex cover with
at most twice as many vertices as an optimal vertex cover. In this course, we will study approximation algorithms, with a number of NP-hard problems as example problems.

Expected learning outcome
After the course, the student is expected to be able to
- give an overview of the problems and techniques studied in the
  course.
- give a precise definition of each of the combinatorial problems
  studied in the course.
- give a precise description and analysis of each of the algorithms
  studied in the course.

Subject overview
Combinatorial algorithms, LP-based algorithms, vertex cover, set
cover, TSP, multiway cut, k-center, knapsack, bin packing,
scheduling.
