Excited to release Part I of Optimizing with Column Generation. Not a draft. Two years of hard work led to 300 pages covering CG principles in depth. Check https://t.co/njDTUaCJmf Your feedback will help us with the forthcoming Part II on advanced techniques!

Another interesting VRP challenge to keep an eye on 👀
We’re thrilled to announce that Dr. Thibaut Vidal’s role in TIG is evolving. He now joins as Challenge Owner, taking an even more active part in TIG’s success. As steward of the Vehicle Routing Challenge, Dr. Vidal will help drive our mission forward by attracting top

CVRPLIB Best Known Solution (BKS) Challenge! We are launching a 30-day competition to push the boundaries of the Capacitated Vehicle Routing Problem (CVRP): https://t.co/LwKYzEU6CE We look forward to seeing the community take on this challenge!

My views on the recent AlphaEvolve's announcement. Did AI just revolutionize matrix multiplication? Does it close the loop of singularity and "doom" human mathematicians? 😬Not quite. What do you think?

Latin America World Model (LAWM 1976) was a system dynamics model aimed at simulating economic, social, and environmental development of third-world countries, challenging the existing "neo-Malthusian" models. Hugo Scolnik tells great stories about LAWM!

I published 4 journal papers from my 4-year PhD. That was considered excellent back in 2000. Today, PhDs and post-docs are pressured to publish 2, 3, 4, ... papers per year to quickly achieve h-index>10. That's madness https://t.co/KRqUxgXogd

Dear @ILjubic Many thanks for the opportunity to visit your group at ESSEC! Perhaps Column Generation will also meet Bi-Level soon 😉
Thanks @ed_uchoa for your excellent talk at @essec OMOR seminar. Your new book on column generation will be a great source of inspiration not only for new generations of #orms researchers, but also for experts and practitioners ! https://t.co/KVNP5EwLC1

The episode also touches on very emotional human issues, his humble family origins, his difficulties establishing himself in academia, and some major personal challenges he has faced in the last 5 years.

Spotlight on Artur Pessoa: an exceptional programmer with comprehensive optimization knowledge, a brilliant mind behind many advances in column generation. He is not easily found at international conferences but his contributions are profound. Know this "hidden figure" in OR!

Visiting LOG UFPB is truly a delightful experience. It might be hard for those from outside Brazil to understand the significant challenges involved in establishing a dynamic scientific group in a region that has faced economic hardships and historical discrimination.
What a joy to host my PhD co-advisor and s.t. guest Eduardo Uchoa (@ed_uchoa) at UFPB! 🤩 He also took the chance to visit the s.t. studio. 😎

"They created a new, faster algorithm for solving ILP in almost the same time as the trivial binary case". Theoreticians consider binary ILP trivial! Sure, you test all the 2^n possibilities 😁 https://t.co/6hehKG9t0j

Integer linear programming can help find the answer to a variety of real-world problems. Now researchers have found a much faster way to do it.

The Workshop on Computational Approaches to Vehicle Routing and the David Johnson Tribute was a real highlight of 2023. We toasted its success in the annual DIMACS poster!
Our annual poster celebrates some of the people and events that made 2023 another great year for DIMACS. We wish you a happy & healthy new year, and we look forward to seeing you in 2024! @pennockd

Starting the year with a complete article on the origins of Column Generation and its use in the Cutting Stock Problem. Amazing discoveries made amidst some of the 20th century's most dramatic events @rrsadykov
