<input type="hidden" /><p>Daniel Dadush,
an Algorithms, Combinatorics, and Optimization (ACO) PhD student at Georgia
Tech based in the H. Milton Stewart School of Industrial and Systems
Engineering (ISyE), was selected as the winner of the 2011 INFORMS Optimization
Society Student Paper Prize for his paper “On the Chvatal-Gomory Closure of a
Compact Convex Set.” The paper was co-authored
with Santanu Dey, assistant professor in ISyE, and Juan Pablo Vielma, who received
his PhD from ISyE in 2009 and was the 2007 recipient of the Optimization
Society Student Paper Prize. Vielma is currently the assistant professor in the
department of Industrial Engineering at the University of Pittsburgh. The prize
is awarded annually at the INFORMS Fall National Meeting for an outstanding
paper in optimization by a student author.</p>
<p>The citation reads:</p>
<p>"The paper shows that the Chvátal-Gomory closure of
compact convex sets is a rational polytope. For the special case of rational
polytopes, this is a well-known result. The new result includes the case of
irrational polytopes and thus resolves a question that was posed by Schrijver (1980)
and had remained open since. Solving this long-open question is already a
wonderful contribution, finally completing the Chvátal-Gomory theory for
polytopes. The paper goes beyond this and also provides a solution for
arbitrary compact convex sets, completing the program started in a paper by Dey
and Vielma (2010) for the case of ellipsoids and continued in an earlier paper
by Dadush, Dey, and Vielma (2011) for the case of strictly convex bodies. The importance
of this contribution lies in providing a foundation for a finite linear cutting
plane theory for convex integer optimization.</p>
<p>The paper uses techniques from convex geometry and the
geometry of numbers in an expertly way. In the proofs, the authors avoid
explicit calculations in favor of soft analysis, including techniques from point-set
topology, which makes the paper particularly elegant."</p>

Convention Center in Charlotte, North Carolina on November 13, 2011. INFORMS,

<input type="hidden" /><p><strong>Juan Pablo Vielma</strong>, a fourth year PhD student in the H. Milton Stewart School of Industrial & Systems Engineering (ISyE), won the prestigious INFORMS Optimization Society Student Paper Prize. The winning paper entitled "A Lifted Linear Programming Branch-and-Bound Algorithm for Mixed Integer Conic Quadratic Programs* was written with his advisors Professors <strong>George L. Nemhauser </strong>and <strong>Shabbir Ahmed</strong>. </p>
<p>The award selection committee praised the paper saying "This paper is an impressive blend of theory, algorithm engineering, and computation that gives us a valuable new tool for solving a difficult and important class of problems.*
</p>
<p>Vielma received his award at the 2007 INFORMS Annual Meeting in Seattle on November 4 where he gave a talk summarizing the contributions of the paper. This recognition is a significant honor for it is the first year that INFORMS Optimization Society has presented a student prize.
</p>
<p>"Scholarly awards of this caliber are always gratifying for the student and his or her advisor(s) and I know that Juan Pablo and Professors Nemhauser and Ahmed are rightly proud of this particular accomplishment,* said Professor Gary Parker, Associate Chair for Graduate Studies. "For me, it also provides strong testimony in justifying the efforts and resources that are needed in order to recruit Ph.D. students like Juan Pablo and to sustain the academic infrastructure in the School that inevitably enhances our ability to compete, fairly, for doctoral student talent at the highest level.*
</p>
<p>Prior to joining the PhD program in ISyE, Vielma earned his BS and MS in Mathematical Engineering at the University of Chile. His research interests include linear and nonlinear integer programming and forestry applications of operations research.</p>
