Our survey on deep learning and polyhedral theory is finally published! pubsonline.informs.org/doi/10.1287/... This was a great opportunity to explain what we have been looking at without the constraints of being focused on a specific technical contribution or page limit.

Today my master’s advisor, Yoshiko Wakabayashi, is being awarded the title of Professor Emeritus at University of São Paulo. She has been a knowledgeable, caring & dedicated member of the Brazilian algorithms, combinatorics & optimization community throughout her career. Congratulations Yoshiko!

Thanks for all the OptiBeer @optimizer.bsky.social @jefflinderoth.bsky.social and for the OptiWine @lauraalbertphd.bsky.social Heading back to Corn Land from Dairy Land after a day packed with very interesting research discussions

Excited to have @thserra.bsky.social here at UW Madison for SILO seminar series.

Thiago Serra posted on his blog what I think are some useful tips on doing presentations. thiagoserra.com/2026/03/03/m...

There are many things about preparing and presenting slides that I keep repeating to students, so I figured that I should put them down in writing. I do think that they help a lot. (And if I am doing it, why not share it more broadly?) thiagoserra.com/2026/03/03/m...

Mark your calendars and start optimizing your resources and schedules: the 2027 International Symposium on Mathematical Programming will be held from July 25 to to 30 in beautiful Amsterdam! Neil Yorke-Smith and I will organize the stream Discrete Optimization with Machine Learning. #ismp2027

Working on (part of) 59 pages and 33 questions of a proof with a 48-hour deadline, but lucky to have Gonzalo Muñoz as corresponding author. Our survey will soon be online at IJoC!

I am happy to share about a new paper with Jiatai Tong, Yilin Zhu, and Sam Burer — which also just got accepted at CPAIOR 2026: Optimization over Trained Neural Networks: Going Large with Gradient-Based Algorithms 1/N

What can’t LLMs do? If you get caught using them for data fitting, you deserve a warning. Mochen Yang talked at Iowa’s Tippie College of Business about the caveats of using LLMs for that purpose. After all, getting gpt-4o to predict 0.1875 entails predicting tokens “0”, “.”, “187”, and “5”! 1/4

As someone who has always been involved with computing, optimization, and AI… I am happy to share that I am joining the editorial board of the INFORMS Journal on Computing as Associate Editor in AI and Optimization! 😎 pubsonline.informs.org/page/ijoc/ed...

The Summer 2026 list of schools has been updated with four new opportunities. You can look for those directly by searching for "Included on January 15"! thiagoserra.com/2026/01/04/s...

Excited to present a new preprint with @nkgarg.bsky.social: presenting usage statistics and observational findings from Paper Skygest in the first six months of deployment! 🎉📜 arxiv.org/abs/2601.04253

Kicking off 2026, here is a new list of summer schools on artificial intelligence, data science, machine learning, and operations research: thiagoserra.com/2026/01/04/s...

I am happy to share a new version of the Surrogate Within A Surrogate paper. This paper shows that we can find better solutions for an optimization problem involving a dense neural network by pruning it. We made an extra effort to clarify our contributions and to expand our experimental evaluation.

Looking for an auspicious PhD? Try it the Iowa way! We have a top-notch department with active research at the intersection of many important fundamental and emerging subjects. There is still time—the application deadline is three weeks away! More information here: tippie.uiowa.edu/phd/phd-busi...

Happy to have contributed to Anna Mitchell’s cover story at The Daily Iowan about data centers in Iowa. You can read it here: dailyiowan.com/2025/12/09/c...

Today I am celebrating the symbolic thousandth citation on Google Scholar.

Next week, I will be participating on a panel hosted by @gurobioptimization.bsky.social about training the next generation of mathematical optimizers. You can join the conversation here: www.brighttalk.com/webcast/1918...

I’m excited to share the materials from my Stanford seminar course, “AI for Algorithmic Reasoning and Optimization”: vitercik.github.io/ai4algs_25/. It covered formal algorithmic frameworks for analyzing LLM reasoning, GNNs for combinatorial/mathematical optimization, and theoretical guarantees.

It's been an absolute pleasure working with Ellen, Madeleine, and their amazing PhD students for the past year on making optimization more accessible with generative AI! I am on the job market this year - check out my website (conlaw.github.io) for more details on what I've been up to.

Please keep an eye out for Connor Lawless (@lawlessopt.bsky.social) on the faculty job market! Connor is a Stanford Human-Centered AI Postdoc, co-hosted by myself and Madeleine Udell. His research combines ML, computational optimization, and HCI, with the goal of building human-centered AI systems.

The 2025 ICS Student Paper Award winner is Hao Hao (CMU) for the paper "Robust Paths: Geometry and Computation," co-authored with Peter Zhang.

The 2025 ICS Harvey J Greenberg Research Award was presented to Braden L. Crimmins, J. Alex Halderman, and Bradley Sturt for their paper "Improving the Security of United States Elections with Robust Optimization."

The 2025 ICS Prize Committee recommended the recognition of two submissions as co-winners of the ICS Prize: (1) Alper Atamtürk, Andrés Gómez, and Shaoning Han (2) Jason Altschuler and Pablo Parrilo

And that’s a wrap for #informs2025 See you next year in San Francisco!

In Hans Mittelmann’s presentation on optimization benchmark results at #informs2025, he raised the point that benchmarking enters a new era with AI being used under the hood by solvers in one way or another.

Thinking of my PhD days, my recollection of Shabbir Ahmed was as one of those senior professors who would come, chat, and give advice to other people’s PhD students in workshops and conferences. He was a nice guy who left this world too early.

Group photo taken at the Resilient Networks session at #informs2025. My @isenbergumass.bsky.social PhD student @ismaelpour.bsky.social presented our paper published recently in ITOR on crop and cargo war risk insurance. This is joint work with Borys Kormych.

I’m recruiting a postdoctoral researcher on a fully funded 2-year contract. The topic is developing and implementing new parallel graph algorithms, with applications to data-driven transportation and logistics. Details and application procedure below ⬇️ Reach out if you have any questions!

The University of Iowa is launching a new ranking of business analytics departments (including equivalent departments in other business schools) at this year’s @informs.bsky.social Annual Meeting. 1/3

Had a fun pre-INFORMS Saturday. First, I joined Kayse Lee Maass and Graeme Warren for the panel Learning and Teaching with Games at the Teaching Excellence and Networking workshop, hosted by Yaren Bilge Kaya. 1/3

Happening right now at INFORMS: Lucas Waddell is talking about our project, which improved how final exams are scheduled at Bucknell University at B406! You can read more about it here: arxiv.org/abs/2509.11031 #informs2025

If the LLM that you use for preparing your job application is the same LLM used by the recruiter on the other side for identifying top candidates, does that improve your chances? Jiannan Xu showed us at #informs2025 Data Mining workshop that YES, it does! Paper: papers.ssrn.com/sol3/papers....

Last week I had the immense privilege of giving the opening keynote talk of the BRACIS - Brazilian Conference on Intelligent Systems #bracis2025 and visiting the beautiful city of Fortaleza for the first time. 1/3

Closing #bracis2025 with mastery, Sandra Avila talked about her journey working on diagnosing melanomas (a type of skin cancer). Interestingly, the story starts with winning a classification contest, and then evolves from her working backwards to figure out what the models actually predicted. 1/N

Evangelos Papalexakis gave an interesting and accessible keynote about latent structure and tensor decomposition at #bracis2025 The identification of latent structure was motivated with the observation from Miller’s Law that we only keep “7 +/- 2” items in memory at any given time time. 1/N
