The Schweitzer contest is uniquely high-level among mathematics competitions. The problems, written by prominent Hungarian mathematicians, are challenging and require in-depth knowledge of the fields represented. The competition is open-book and competitors are allowed ten days to come up with solutions.
The problems on the competition can be classified roughly in the following categories: 1. Algebra 2. Combinatorics 3. Theory of Functions 4. Geometry 5. Measure Theory 6. Number Theory 7. Operators 8. Probability Theory 9. Sequences and Series 10. Topology 11. Set Theory
