This graduate course will study the use of randomness in
algorithms. Over the past thirty years, randomization has become
an increasingly important part of theoretical computer science.
The tentative outline for the course is as follows:
- Basic probability; the minimax principle; limited independence
- More advanced concentration of measure: subgaussian and subgamma variables
- Balls in bins; negatively associated random variables
- Hashing: universal, perfect, cuckoo
- Fingerprinting; Bloom filters
- Network coding; edge connectivity
- Graph sparsification
- Parallel algorithms; symmetry breaking
- Randomized approximation algorithms
- Streaming algorithms
- Stochastic gradient descent; SVRG
- Random walks: cover times, markov chains, mixing rates.
Mathematical maturity and comfort with undergraduate algorithms and

||In each class, two students will be assigned to take notes.
These notes should be written up in
a standard LaTeX format before
the next class.
||You may find the
Algorithms by Motwani and Raghavan to be useful, but it is not required.
There will be a homework assignment every 1-2
Collaboration policy: You are encouraged to
collaborate on homework. However, you must write up your own
solutions. You should also state the names of those you
collaborated with on the first page of your submission.
