Pretty late to the party, but I was honored to receive the Robert Faure prize 2026 from the French Operations Research Society! matbesancon.xyz/post/2026-04...

Yeah sure AGI but when will train platforms apply reduction cards correctly on a trip?

Inria (sadly not here yet) will be preparing candidates for the Marie Skłodowska-Curie Postdoctoral Program scholarships. The institute also centralized a whole list of hosting teams (including GHOST, mine!) with potential topics: www.inria.fr/en/marie-skl...

Don't get me wrong I have nothing against doing that theoretical upper bound research. The drama is that I struggle to find real improvements to maxflow (or more generally flow?) algorithms that came from this theoretical progress. Isn't that one role that theoretical algorithmic should fill?

<academic rant> I am always amazed and annoyed at the same time that there is a research field of "algorithms" in which you need to spend an enormous amount of time to understand if any new method has a slim chance of ever being run

Early Christmas for MIP folks!

The SCIP 10 optimization suite has many new interesting features and is fully open source. For binaries and downloads, check www.scipopt.org/index.php#do...

I got hyped and then read the last line 😑

Probably my lazy french brain but some journal allowing delays in paper reviews for "exceptional personal circumstances (e.g. vacation)" gets my teeth grinding hard 😬 Of course with 3 vacation days per year I guess that falls into exceptional

Barely have a permanent position and already called old by the new generation, academia is brutal

- Mixed-integer optimization is so second-nature to us operations researchers, it's easy to forget most people approach their combinatorial problems through polyhedral relaxations - and conic formulations, of course - of course

I don't know if there is a North-South divide on that, but have to say that the train in Italy has been one of the best 🚆 experiences for me this year (on the Torino-Bologna-Rome line)

I know what I'm reading on my train trip this week! Sophie and Eleon bridging the gap between analysis of algorithms and real-world computational optimization 🎉

My usual system, inspired by my PhD advisors, is first author (quite often a younger scholar), and then the rest in alphabetical order. This means I'm typically the second author, minimum contribution according to Google Scholar it is 😑

Very clear and bold welcome speech by Prof. Laudani from the city of Bologna council at #ECAI25!

Gosh I hit the second root

Life goal: being so good at extreme irony-ing you get second degree burns

Authors generating pieces of their paper with LLMs: this is saving some research time in the same way throwing garbage out the window is saving home chore time. And yes the comparison is exactly my feeling after the tenth useless adjective and repeated sentence.

BTW if you're at the conference and looking for your next research adventure in computational optimization, come say hi!

My first @juliacon.bsky.social in too many years, very excited to see what people are building, using, combining, experimenting

Apercevoir @edwyplenel.bsky.social à la gare, le trajet est déjà une première classe 😱

Academics: I'm preparing an informal talk to junior scholars on preparing for the faculty job market. What are things nobody told you and that you wished you knew?

Resisting the urge to do my next talk slides in typst and end up debugging at the last minute

@neuripsconf.bsky.social decisions and stats are out. Definitely sad that a great initiative was set up but NOT what it should be: a third option to avoid 5000 authors burning kerosene crossing the world to present 8 pages

Being a journal website in STEM should not need so many things: 1. a page for each paper 2. a download paper button 3. a get citation as bibtex option Why on earth does INFORMS not have 3? One can only copy the text format of the citation it seems

@thserra.bsky.social doesn't write titles, he writes punchlines 👊

Leaving KTH Today after a wonderful stay following the Global Optimization Workshop, see you soon Sweden!

The Stockholm Global Optimization Workshop (STOGO25) starts today, looking forward to Martin's slides and photos!

The blog post by T. Tao should give a good shake to the last people thinking the scientific apparatus can operate as usual across the pond. But:

Want more open-source software and scientific computing in your life? Get your ticket for JuliaCon Local Paris 2025 before the end of the early bird pricing! We have an impressive lineup of keynotes, starting with Professor Laura Grigori (EPFL) and not stopping there! juliacon.org/local/paris2...

I'm probably going to regret this rabbit hole... do people here have a text editor they like that is: - not modal - configurable enough I've been using micro for almost 10 years but some go features make it a bit of a pain on some systems (don't ask me how I found out)

Slides for #EuroMIP25 are online!

To push that even further, is NeurIPS becoming a pay-to-publish journal in disguise? 🤡

I'm glad they're setting things up for our transportation research program ACME acme-mobidec.github.io

There is a current call for research fellows (temporary position with a generous package) at MIAI, the Grenoble AI Cluster (miai-cluster.univ-grenoble-alpes.fr/en/). If people are interested in working around optimization and learning within a dynamic group, ping me!

This is especially important in communities like ours always dancing between different publishing processes: MIP is not quite conf proceedings-driven, journals are often too slow (and offer more credential than visibility?). Special editions offer an interesting third path to publication!

A resounding success for the first #EuroMIP25, strong interest from participants to learn from each other on the whole spectrum of MIP research, all very strong signals that the community is in demand for the format and topic!

Sophie Demassey starts the last day of EuroMIP25 with a talk on network design for water management

Monique Laurent opens the second day of #EuroMIP25 with a presentation on Semidefinite approximations for bicliques and biindependent pairs. The focus is on measures involving the size and balance of independent sets in bipartite graphs such as their sum or product. #EuroMIP25 #orms

Second day of #EuroMIP25 starting with Monique Laurent speaking about biindependent sets in graphs and SDP, with a hybrid board+slides format!

I don't know if I have the AI crowd here but weren't ECAI reviews supposed to drop today?

The new version of the cutting plane game just dropped: bigkwii.github.io/cutting-plan...

New work on FW just dropped! We look at corrective Frank-Wolfe, aka algorithms which optimize over a constrained set by alternating between computing a new vertex and optimizing over the convex hull of the vertices found so far
