Thank you! And yes agree about difficulty. As for lessons… this is broad/vague but it’s like with the work I do on race in the criminal legal system: powerful actors being NOT explicitly biased isn’t enough. They need to actively counteract biased that land on their doorstep.

🚨 80% of Nobel Prizes go to folx in 5 countries. Why? We analyzed 75 years of prize committees, nominators, nominees, and laureates... a network of 500k edges. Turns out nominators choose compatriots at 5x the expected rate — amplifying geographic bias. Read: osf.io/preprints/so... #AcademicSky

13 PhD positions in in applied #maths, #orms, engineering, or CS within the ALMOA consortium -> study applications of European and international relevance in areas such as sustainable energy systems, green gogistics, etc. almoa.aau.at?page_id=53

The first MIP solvers have told me that they will try our modified perturbations. Hopefully its as big an improvement in practice as in theory 🙏

📢 Semi-Plenary Speakers for #ISMP2027! We are pleased to announce the semi-plenaries for the 26th International Symposium on Mathematical Programming. Join them to explore advances, challenges, and opportunities in mathematical optimization. 🗓️ July 25–30, 2027 📍Amsterdam 🔗 ismp2027.mathopt.nl #MOS

MIP European Workshop 2 October 19-21, Rome This is my favorite event in the world. Save the date

I have started using chuuchuu to keep up to date on my train schedule, as well as when planning routes. It is very nice

Congrats to men everywhere for continuing your Turing Award streak

GAMS is doing a new MIP benchmark. They have a clever workaround for DeWitt clauses to include commercial comparisons

I had assumed that the harm from DOGE cuts would fall hardest on non white men but this is astonishing. Read the rest for profiles of hardworking women who just wanted to help the public, and who were hastily fired by presumably a white adolescent empowered by Musk/DJT.

As it did four years ago, the international mathematics community faces a clear choice about what its highest values and aspirations mean. docs.google.com/forms/d/e/1F...

Since SIGACT is on X but not BlueSky,* advertising the SIGACT Distinguished Service Award here, "given annually to an individual or group who has made substantial service contributions to the Theoretical CS community" #TCSSky ⏰ Nominate by April 30! sigact.org/prizes/servi... *I know. Ugh.

You've probably heard of hit game enclose.horse by now. Place 10 segments of wall to make the horse unable to escape, while enclosing maximal surface area. Obviously in NP, unclear if its NP-complete. Time for some mathematical optimization 🧵

enclose.horse is a game in which you enclose a horse. You start with a map like this with water, fields, and horse. dynomight.substack.com/p/horse

Last week this game gave away the optimal value for all puzzles, and everyone I spoke with said that it killed all the suspense. That means what's interesting is not just finding a good solution, but also convincing yourself of its quality

It was my pleasure speaking with @nutanlimaye.bsky.social about her podcast "Life of a Researcher". Check out the interview in the post below and listen to her great podcast. podcastaddict.com/podcast/life-of-a-researcher/4111736

Welcome to BlueSky, @eatcs.bsky.social! I suggest everyone to follow the new account to stay up to the date with news from the European Association for Theoretical Computer Science.

Ig Nobels more locationally conscious than most non-parody conferences

We all know what the results will be

I highly recommend this column by Hongseok Yang and two of his students giving a formal logic take on a powerful method from extremal combinatorics.

Sauce a follow while we figure out the right way to post online as a professional org haha

The EATCS is now on bsky!

Harrowing. Draws on work by @oonahathaway.bsky.social and @tomdannenbaum.bsky.social

Book recommendation: Street-Fighting Mathematics by Sanjoy Mahajan I read this early in my PhD, and it's been with me ever since. Chapter 1 grants a superpower that I cannot imagine living without.

It’s an incredible honor to be a plenary speaker at #ISMP2027 alongside these amazing optimizers. I look forward to seeing all my optimization friends in Amsterdam!

Giving talks IRL is easy. Giving talks on Zoom is very hard. That's why I like recording for Youtube: it has all accessibility benefits of online without the pain of videoconferencing

The Zoom link for Sophie's talk on "Analyzing the Simplex Method by the Book" is now available on our website. See you tomorrow, 1pm ET! www.tcsplus.org/welcome/next...

so whats up with that group Math, Inc.? the vibe they give off is horrid, but also i don't get why they are

It's been almost two years and still I hear of people calling my IPCO lecture a scandal 😊

Do I have any friends who can read Hebrew? I am curious what the Israeli courts use CPLEX for

i would self-diagnose with physics envy if it wasn't so stigmatized

Come see me speak about the new era of simplex method theory. Wednesday!

In every action in every unjust war, operations research plays a role. We teach our students how to make this happen

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

📢 #ISMP2027 comes to Amsterdam! The 26th International Symposium on Mathematical Programming will be held July 25–30, 2027. Join researchers from around the world to discuss advances, challenges, and opportunities in the theory and practice of mathematical optimization. 🔗 ismp2027.mathopt.nl #MOS

Have any percolation theorists studied enclose.horse? Gamers want to know the expected score on infinite random boards

It seems all Kansas-issued trans drivers' licenses are invalid, effective tomorrow It is now illegal for trans people to drive a car until they surrender their license at a DMV (that most will need to drive to) and have it reissued with the wrong gender marker This was never about woman's sports

The American Chemical Society has a very cool YouTube channel. They make short videos about different papers in their journals

Did you know? Python plotting library matplotlib uses an LP solver to figure out its subplot layouts

Friendly reminder that someone was paid to do the math, literally, and that person was probably taught that math was apolitical.

New blog post! I write about various hard-of-hearing accommodations I've had at various conferences, their ups/downs, and things you can do to help hard-of-hearing people at conferences. matthras.com/2026/02...

Question: 1. Are you familiar with Polylog on YouTube? 2. If so, how did it impact you?

Concentration camps: “For 280 days we haven’t eaten a single piece of fruit, banana, apple, orange, or anything fresh. We are all in one big room with no doors or windows. We can’t see any grass or trees. We are all constantly sick."

Omg, thread, I love it when people are so thorough

Springer Nature publishes chatbox-generated BookToks now 😭

Our paper will be in STOC this summer! 🌎
