2015 Review of our Chapter
Our annual report to INFORMS was due yesterday. What a year! After compiling everything we did, it would be a waste not to share it more publicly. Except for the chapter and fora breakfast at the INFORMS Annual Meeting, we don’t know much of what happens elsewhere.
The big things
We had two major events in 2015. Thanks to sponsorship from the Tepper School of Business, we had a seminar and a tutorial with MIT students Joseph Huchette and Miles Lubin: “JuMP, a modeling language for mathematical optimization”. We also had a happy hour followed by an ORMS job market panel with alumni that were in Pittsburgh to attend the ISMP 2015 conference. The panelists included Amitabh Basu, Fatma Kılınç-Karzan, Qihang Lin, Marco Molinaro, Selvaprabu Nadarajah, Viswanath Nagarajan, and Negar Soheili.
Among our social gatherings, we had a joint happy hour with the University of Pittsburgh chapter:
Besides that, we had two “pizza social” events to talk about what the chapter could do and a picnic on our elections day, which also served to welcome the incoming PhD students:
Our (short) history
The CMU INFORMS Student Chapter is quite young. In fact, I still remember Aleksandr Kazachkov going down the hall asking which students were INFORMS members to submit the chapter application, aiming to bring to CMU something that meant a lot to him as an undergrad in Cornell. We took off in June 2014 gathering students from the doctoral programs in ACO (Algorithms, Combinatorics, and Optimization), OM (Operations Management), and OR (Operations Research) at CMU’s Tepper School of Business, which together account for 24 students (about 4-5 students per year). With time we also attracted students from Computer Science, Math, Chemical Engineering, and Tepper MBA students. We also put some effort into attracting undergraduate students at the activities fair last Fall:
Although short in existence, we have found some interesting niches thanks to the effort of our members. In particular, thanks to Tarek Elgindy, we have started our main tradition: the Monday discussion dinners. Tarek felt that we were often unaware of each other’s work and lead himself the first discussion. This thing gained momentum and we had 20 discussions throughout 2015. Some people spoke once, twice, or even more (me included). Sometimes this was about our research, something we were learning about, or even experiences like summer internships and having attended the INFORMS Doctoral Student Colloquium. You can have an idea by the list below:
- 01/19 - Tarek Elgindy: Stochastic network design problems
- 01/26 - Vince Slaugh: Managing rentals with usage-based loss
- 02/02 - Ryo Kimura: Petri nets
- 02/09 - Thiago Serra: Disjunctive cuts
- 02/23 - Aleksandr Kazachkov: Algorithms, complexity results, and open problems in Vertex Enumeration
- 03/02 - Christian Tjandraatmadja: Aiming and shooting: Thoughts on an empirical exploration of facets
- 03/23 - Tarek Elgindy: A cryptocurrency which changes the proof-of-work component used in the bitcoin protocol
- 03/30 - Jeremy Karp: Primal-dual methods for online problems, including online matching
- 04/06 - Tony Johansson: Random minimum matchings and Riemann’s zeta function
- 04/13 - Ryo Kimura: Robust scheduling with uncertain processing times
- 04/27 - Thiago Serra: Generation of cutting planes from non-convex lattice-free sets and some of empirical results obtained so far
- 05/18 - Gerdus Benade: The minimum bandwidth problem
- 09/14 - Jeremy Karp and Christian Tjandraatmadja: Summer internships
- 09/21 - Christian Kroer: Inner Approximation of the Realizable Polytope: Solving Hard Prediction Market Pricing Problems
- 10/05 - Aleksandr Kazachkov: Final point cuts
- 10/12 - Siddharth Singh: Delay announcement for admission control under competition
- 10/19 - Thiago Serra: Cadoux and Lemarechal’s Reflections on generating (disjunctive) cuts
- 11/16 - Leela Nageswaran and Thiago Serra: INFORMS Doctoral Student Colloquium
- 12/10 - Xin Wang: Green technology development and adoption: Competition, regulation, and uncertainty - A global game approach
- 12/16 - Christian Tjandraatmadja: Relaxed decision diagrams and integer programming
Thanks to Alex Kazachkov, since 2014 we have been running review sessions prior to important seminars, where we go over the paper that will be presented or some material that would help the students follow the talk. The feedback about these gatherings has been great, since the preliminary discussion prevents students from getting lost too soon in more advanced talks. We had 5 of those last year:
- 02/13 - Daniel Schmidt (University of Cologne, visiting CMU)
- 03/06 - Vineet Goyal (Columbia University)
- 03/20 - Joseph Huchette and Miles Lubin (MIT)
- 03/26 - Egon Balas (CMU)
- 04/10 - Robert Vanderbei (Princeton University)
The next big things
So far we have not used the INFORMS Speakers Program and neither have we targeted our MBA audience properly. Our goal is to use this program to bring speakers with vast experience in the industry. We are also looking into interacting more with the chapters in our region, keeping our connection to UPitt and possibly going further. Hopefully, the 2016 report will have its own lot of new ideas that worked out.
The people behind it
Our chapter is greatly indebted to the efforts that Alex Kazachkov has put since it all started. Our main events in 2015 were his idea, not to mention many of the social gatherings. In addition, Tarek Elgindy’s discussion dinners became our identity as a group. There are many other people now on the board doing a great job. Alex and Tarek can be sure we are taking good care of what they started!
We are also grateful for the constant support and insights from our faculty advisor, Professor Fatma Kılınç-Karzan.
