Lecture Course "Approximation Algorithms"

Summer term 2023

(Module V4C2 and MA-INF1201)

Approximation algorithms are polynomial-time algorithms that guarantee to find a feasible solution that is optimal up to a factor of k. For some NP-hard problems, k can be chosen arbitrarily close to 1, for others there is a best possible constant, and for some problems there is no such constant (unless P=NP). We analyze the approximability of various classcial NP-hard combinatorial optimization problems, including the TSP, set covering, knapsack, bin packing, and satisfiability problems.

This course will be in English. Most of the course will be based on the following book:

The following textbooks can also be recommended: All these books are available in our library.

Prerequisites: Combinatorial Optimization, in particular basic knowledge in graphs, linear programming, network flows, matching, and NP-completeness; see, e.g., Chapters 1-15 of the book by Korte and Vygen (see above)
Class Hours: Tuesdays and Thursdays 14:15-15:45
Exercise Classes: Wednesday 14-16, starting from April 12
Oral exams: Tentative dates: July 27-28 and September 25-26
