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.
Beyond Smoothed Analysis: Analyzing the Simplex Method by the Book
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...

I have been enjoying this podcast lately. It's about the very early history of electronic computers.

My only complaint is that it skips over the impact of and for linear programming. Luckily there are linked sources that give an extra glimpse

Today, if someone publishes 30 papers per year, we all know that those papers probably aren't very good.

But Erdos published 1500 papers in his lifetime, and he is broadly respected. How do we reconcile this?

The Mathematical Society of France will not be at the 2026 International Congress of Mathematicians, to be held in Philadelphia.

This is great news. I hope other mathematical societies pull out as well. It would help if the @amermathsoc.bsky.social also declined to participate, in solidarity.

100% agree. Especially since we have author IDs that are matched to the papers when they are claimed!
Arxiv's lack of commitment to its author page feature is so disappointing. Why, when I click on the link that is an author's name, am I sent to a search page of "F. Lastname"? This is ridiculous

My name is so boring this is basically unusable to search me, and I've frequently found it frustrating as a searcher, too.

If you liked that article about @sophie.huiberts.me research, I think you might like this video of one of her research talks. Maths is accessible, but notably into the ethics of applications of the simplex method: minimum wage debates and supplies allowed into Gaza.

"Nearly 80 years later, the simplex method is still among the most widely used tools when a logistical or supply-chain decision needs to be made under complex constraints."

only half followed the description of the simplex method in here but super interesting anyways
