*Who:*           Yury Makarychev, TTIC



*Title*:            Shortest Path, Asymmetric TSP, and Group Steiner Tree
with Vector Costs


*Abstract:* We study analogues of classic combinatorial optimization
problems – Shortest Path, Group Asymmetric TSP, and Group Steiner Tree –
with vector costs. In these problems, we assume that every edge has an
associated cost vector with non-negative components. We define the cost of
a feasible solution as follows. We add up cost vectors for all the edges in
the solution and then compute the \ell_p-norm of the obtained vector.

We present polylogarithmic-approximation algorithms as well as hardness of
approximation results.

Based on joint work with Max Ovsiankin and Erasmo Tani.

*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 for students
seeking research topics and advisors and for the general TTIC and
University of Chicago communities interested in hearing what their
colleagues are up to.
