This course will be ideal for someone wanting to build a strong foundation in the theory and practice of algorithms for
processing Big-Data. We will discuss advanced data structures and algorithms going beyond deterministic setting and emphasize the role
of randomness in getting significant, often exponential, improvements in computations and memory.
COMP 182 or equivalent required. COMP 382 is useful but not required. Basic Knowledge of
Probability. Knowledge of programming is required. Capability to manipulate primitive data structures such as arrays, list, etc. will
be needed for assignments.
Most of the materials (scribes and slides) needed will be posted on this website.
Some of the materials are fairly new and textbook is yet to be written.
A Nice Book to have is "Probability and Computing: Randomized Algorithms and Probabilistic Analysis
