I am begging you, stop using LLMs to write your papers it is horrible to read and causes an instant DNF.

Sally Dong talked at the #mip2026 workshop about solving linear programs more efficiently by identifying underlying graphs associated with their constraint matrix. #orms 1/N

So one consistent thread is: we have no agency over our own behavior in the presence of temptation (zoning off during lectures, checking a phone in class, using gen AI), and that's your problem to solve. I know that structural interventions that reduce temptation are legitimate pedagogy but ugh.

'Beltsville Agricultural Research Centre', Maryland - I was privately commissioned to memorialise the BARC by a past employee after learning it will be shut down by the USDA after over 100 years of research. They wanted to focus of this aerial embroidery to be the field plots... 1/3 (see thread)

We have always had oral exams as part of our OM/MS PhD program @isenbergumass.bsky.social, with an oral exam being an important component of the core exam, the comprehensive exam, and also the dissertation proposal defense, plus the dissertation defense! apnews.com/article/coll...

Perfect homework, blank stares: Why colleges are turning to oral exams to combat AI

A growing number of U.S. college instructors are turning to oral exams to help combat an AI crisis in higher education.

It turns out, trains are very complicated and need simplification.. Today i had a look into a >300 page book on railway optimization and the idea of a train having to accelerate was only mentioned 10 times, none of them in the sections about operational optimization (so closest to "real physics"). 🚂

Yesterday we organized a presentation session about teaching practical hands-on courses for the Center of Algorithmics and Optimization (algoopt.rwth-aachen.de) at RWTH Aachen.

Question for #orms people: do you know any problem-specific cutting planes that are not too hard to explain and separate and would improve performance compared to a baseline MIP solver (e.g. SCIP, Gurobi)? Asking because its more fun for students if they implement something and it helps performance

ICE tear gassed a bunch of children on Saturday. This was a massive escalation of force. They were shooting tear gas at the back of the crowd, it took these unmasked people maybe 3-5 minutes in the cloud of tear gas to escape in without trampling. www.theverge.com/policy/87278...

ICE is afraid of children protesting

“Next time, I’ll be back with a gas mask.”

Petition that Linkedin adds a "SLOP" button and if a some percentage of readers hit it, the poster gets prevented from posting for a time. I can't take another "Suddenly the conversation changes." and sentences with an average length of four words as if you had to turn in your brain when logging in.

in the morning, Eduardo Uchoa presented the development of branch-and-price for vehicle routing in our column generation class; in the afternoon, together with Marc Pfetsch, we discussed future developments in SCIP -- a happy and productive day for us computational optimizers #orms

Does there exist a commonly used public instance benchmark set for robust optimization? Or sets of instances which are frequently used within the literature?

The simplex algorithm is super efficient. 80 years of experience says it runs in linear time. Nobody can explain _why_ it is so fast. We invented a new algorithm analysis framework to find out.

Narrowing the gap between theory and practice is a longstanding goal of the algorithm analysis community. To further progress our understanding of how algorithms work in practice, we propose a new alg...
