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 (이다빈) gave a talk on the generalization of the Chvátal-Gomory closure at the Discrete Math Seminar
On March 17, 2020, Dabeen Lee (이다빈) from IBS discrete mathematics group presented a talk on his result proving that the closure of a polyhedron by some generalization of the Chvátal-Gomory cuts gives a polyhedron. The title of his talk is “On a generalization of the Chvátal-Gomory closure“.
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.
Dabeen Lee (이다빈) presented his work on algorithmic problems of finding a clutter minor at the Discrete Math Seminar
On July 16, 2019, Dabeen Lee (이다빈) from IBS Discrete Mathematics Group presented his work on identifying a clutter minor related to ideal clutters at the Discrete Math Seminar. The title of his talk was “Integrality of set covering polyhedra and clutter minors”.
