Course Overview: Randomness is extremely useful in computer science. Algorithms that make random choices during their execution, known as randomized algorithms, are often faster or simpler than algorithms that don't use randomness. Examples include Quicksort, primality testing, and Monte Carlo simulations. However, such randomized algorithms usually come with a small probability of error, so it is important to bound this error probability. In this undergraduate course, we develop tools and techniques to design and analyze efficient randomized algorithms. This course is theoretical and mathematical; there will be no programming assignments. Each section of the course is built around a method, with example applications to randomized algorithms. We list the topics below.
