Topics in Randomized Algorithms
University of California, Los Angeles
Abstract
This talk is a general overview of the use of randomization to various
types of algorithmic problems, particularly of a graph theoretic nature.
We introduce with some examples on MinCut and MST, illustrating the
benet of simplicity. We continue with random walk based methods both to
illustrate complexity bounds for the randomized logspace class, and to
give intuition for randomized approximation schemes for hard counting
problems. This brings us to a major open question on whether or not
there is a gap between randomized logspace and deterministic logspace:
Namely, to what extent may we derandomize?
Graph theoretic techniques based on expanders are useful throughout these
questions. Finally, we also mention some problems in the distributed
algorithmic setting where, in one case, a provably exponential gap in
time complexity exists between randomized and deterministic versions,
and in another case, literally the deterministic version is impossible
to solve in general whereas a randomized approach is both possible and
uncomplicated.
