Dabeen Lee (이다빈) gave a talk characterizing the submodular structure in the mixed-integer program arising from joint linear chance-constrained programs at the Discrete Math Seminar

On September 7, 2021, Dabeen Lee (이다빈) from the IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar characterizing the submodular structure in the mixed-integer program arising from joint linear chance-constrained programs with random right-hand sides and finite sample space. The title of his talk is “Mixing sets, submodularity, and chance-constrained optimization“.

Dabeen Lee received the INFORMS Optimization Society Student Paper Prize on October 20, 2019

On October 20, 2019, Dabeen Lee (이다빈), a research fellow at the IBS discrete mathematics group, received the 2nd place prize in the INFORMS Optimization Society Student Paper Prize. This prize was established in 2006 by the Optimization Society of the Institute for Operations Research and the Management Sciences and is awarded annually at the INFORMS Annual Meeting for the most outstanding paper in optimization. This year, the INFORMS Annual Meeting was held in Seattle, USA.

Dabeen was awarded for the paper co-authored with his Ph.D. advisor Prof. Gérard Cornuéjols, titled “On some polytopes contained in the 0,1 hypercube that have a small Chvátal rank“. This paper was published in Mathematical Programming in November 2018.
