The course covers the use of randomness in design of efficient algorithms. Use of randomness allows to solve problems more efficiently or even to solve problems that are otherwise intractable. The course covers techniques for design of randomized algorithm, demonstrated on concrete problems. We assume knowledge on the level of the courses NDMI084 Introduction to approximation and randomized algorithms and NTIN022 Probabilistic Techniques.
Aim of the course -
Last update: IUUK (11.05.2015)

Teach the students selected techniques of use of randomness in algorithms and of analysis of such algorithms.
