Probabilistic techniques are a major tool of discrete mathematics, they are also frequently used in design and analysis of algorithms and other areas of computer science. The lecture introduces basic notions, methods, and estimates and illustrates them on examples from computer science and discrete mathematics.
Aim of the course -
Last update: IUUK (04.05.2015)

Student who takes the class will learn to actively use a modern

probabilistic techniques in discrete mathematics and computer science,

including the probabilistic method.

Course completion requirements -
Last update: doc. RNDr. Martin Klazar, Dr. (22.09.2020)

For getting the credit from tutorials, the students are required to get at least 50 points from homework. The total number of available points will be at least 180. There is no provision for repeated attempts for the credit. Credit from tutorials is a necessary condition for an attempt to pass an exam. Both exam and the tutorial test may be in person or in distant mode.
