2 Degree Plans – Discrete Models and Algorithms
Coordinated by: Department of Applied Mathematics
Study branch coordinator: Doc. RNDr. Martin Klazar, Dr.
Specializations:
- – Discrete mathematics and algorithms
- – Geometry and mathematical structures of computer science
- – Optimization
The study branch Discrete Models and Algorithms provides education in the area of discrete (meaning non-continuous) mathematical structures used in Computer Science. It deals also with combinatorial (and other) algorithms and with modeling phenomena and processes by means of such structures and algorithms. In the specialization Optimization it puts emphasis on solid grasp of various kinds of optimization. The study branch enables to its graduates to be in contact with current scientific results and ideally it prepares them for independent research activity.
The graduate knows in depth discrete mathematics and discrete structures used in computer science and can model, using algorithms, various phenomena and processes. According to chosen specialization the graduate has advanced knowledge in one or more of the areas: combinatorics and graph theory, random techniques and methods in discrete mathematics and algorithms, algebraic and topological methods, and finally optimization of various kinds. The graduate can use this knowledge in research when solving difficult theoretical and practical questions in the area of applied mathematics and computer science, in technical and economical practice, and in interdisciplinary research. The graduate can work in research and development in either academia or industry in any position requiring logical reasoning, analytical capabilities, an algorithmic approach, and the exploitation of modern methods of computer science.

^{1}For specializations Discrete mathematics and algorithms, Geometry and mathematical structures of computer science we recommend the course NDMI073; for the specialization Optimization we recommend the course NOPT018. After completing one course from Set 2, the credits are counted for that set and the minimal credit requirement for Set 2 is satisfied. If the student completes both courses from Set 2, the credits for the second course are counted for Set 1.
