# UT Algorithms and Computational Theory Group

## Research Themes

The algorithms and computational theory (ACT) group focuses on the
theoretical foundations of computer science. The current research
interests of faculty in the group include algorithm design, complexity
theory, parallel and distributed computation, graph theory, randomized
computation, computational learning theory, probabilistic methods and
combinatorics. A major focus of the group is on the design and
analysis of provably efficient algorithms for solving fundamental
computational problems, where efficiency can be measured in terms of
different resources such as time, space, number of processors, and
number of random bits. We also have strong connections to application areas of theoretical CS such as data mining and computational biology.

## Seminar Series

The ACT Seminar usually meets on Fridays at 11, and features research talks,
problem solving sessions, and discussion of recent theory research results.

## The `algorithms' Mailing List

The algorithms mailing list is an electronic mailing list
on which ACT seminars are announced.
If you are part of the UT community
can add yourself to this mailing list by sending an e-mail
message to udb"at"cs.utexas.edu; please describe your UT affiliation along
with your request to be
added to the algorithms mailing list. You can remove
your name from this mailing list at any time by sending
a message requesting removal to udb"at"cs.utexas.edu.
