The student gains the ability to solve combinatorial problems in practice. Necessary parts of complexity theory, the theory of NP-hard problems and their approximation are presented in a simple manner, followed by the most popular class of heuristic algorithms. Practical assignments build up intuitive insight into the heuristics.
