Course description:
Combinatorial optimization problems are concerned with the efficient
allocation of limited resources to meet desired objectives when the
values of the variables are restricted to be integral.
Combinatorial problems arise in various applications, e.g.
airline
crew scheduling, manufacturing, network design, cellular telephone
frequency design and optimization problems on graphs.
The course deals with polynomial-time solvable combinatorial
optimization problems. Many of these problems are special cases of
linear programming problems.
The following subjects are discussed:
- Shortest paths and trees.
- Polytopes, polyhedra, Farkas' lemma and linear programming.
- Matchings and covers in bipartite graphs.
- Menger's theorem, flows and circulations.
- Non-bipartite matchings.
Prerequisites:
Basic knowledge (bachelor level) of linear algebra and graph theory.
