Title: Recent Developments in Sequence Alignment Algorithms

Abstract:  Similarity measures are some of the most practical problems in
computer science, yet they are unbelievably challenging from a theoretical
standpoint. One of the notable examples is in computational biology when
one wishes to measure the similarity of two DNAs. When the two DNA's are
modeled with sequences of characters, the problem is known as the
celebrated edit distance problem. While the classic algorithm solves edit
distance in quadratic time, it was left open for the past few decades
whether a truly subquadratic time algorithm can approximate the edit
distance within a constant factor. This question, along with several
related problems are answered in recent years thanks to a novel technique
that utilizes triangle inequality for the computation of edit distance. In
this talk, I will explain this technique and show how it answers
these fundamental questions.

*Research at TTIC Seminar Series*

TTIC is hosting a weekly seminar series presenting the research currently
underway at the Institute. Every week a different TTIC faculty member will
present their research.  The lectures are intended both for students
seeking research topics and adviser, and for the general TTIC and
University of Chicago communities interested in hearing what their
colleagues are up to.

To receive announcements about the seminar series, please subscribe to the
mailing list: https://groups.google.com/a/ttic.edu/group/talks/subscribe
