📢 Calling job market candidates!
Apply for the Job Market Showcase Track at the 2026 INFORMS Annual Meeting in San Francisco (Nov 1–4). Senior PhD students, post-docs, and recent PhDs can connect directly with potential employers.
🗓 Deadline: April 30, 2026

Peer review has become problematic. The biggest issue is reviewers making incorrect statements & the editor overseeing their work failing to act. Plus, if you forget to cite their paper, they will/may reject the manuscript, and then your only choice is to submit elsewhere, starting all over.
Instead of using methods of branch & bound for solving the underlying MIP, we use global optimization meta-heuristics, in particular: Backtracking Adaptive Search (see Zabinsky's text, 2003), Simulated Annealing (Alrefaei and Andradottir, 1999), and a traditional Genetic Algorithm.
Congratulations!
Research of my PhD student Joshua A. Afari, co-advised with Dr. Robert Marley, and with Dr. Jiaqiao Hu of Stonybrook Univ. as co-author. #Gratitude to all. The novel idea here is to solve the unequal-areas layout problem while reducing dead space. Open access: Read: link.springer.com/article/10.1...
If anybody has questions about the codes, please don't hesitate to contact me. We're working on converting these codes to Python, given how common the problem is in industry. But please note: These codes already run in the open source solver: Octave.
The codes and a tutorial to use the codes are provided at the following link: simoptim.com/codes/tutori...

I don't disagree. There should have been a condition of repayment after the business became successful. Their track record has not been one of making endless profits & giving enormous salaries to top leadership with regular layoffs of lower-level employees.
The Tata firms are worth billions but no Tata manager has become a billionaire. The Tatas pay their employees well---good healthcare & retirement benefits. They have not evaded any taxes as far as I know. My first job out of college was with the Tatas where I learned the basics of quality control.
I remember reading about the two atomic bombs dropped on Japan in an HS lesson. I had assumed that we would move towards peace with time. But that never happened: nuclear submarines, long-range missiles, and now drones.
Unfortunately, successful firms in the U.S. keep becoming larger, leading to that unhealthy situation.
That's awesome. I get a message from a former student unfailingly at every new year. And messages on my birthday. Always a good feeling!
I used to have a stack of thank-you cards when I first started teaching in Colorado. For some reason, I stopped in my second job, but I think I should buy a stack again. You're right---there are many to whom we owe gratitude.
Even back as an undergrad in Mechanical Engineering, I found myself drawn to a specific thread: Optimization.
Really loved the mathematics in Mechanical Engineering but found systems and algorithms more fascinating! Delighted to support #ORAwarenessDay
Oh truly horrible!! Condolences to those who lost loved ones! I've traveled by some of those trains in Spain. They're incredibly fast. I hope lessons are learned from this disaster.
“Uruguay did what most nations still call impossible: it built a power grid that runs almost entirely on renewables—at half the cost of fossil fuels. The physicist who led that transformation says the same playbook could work anywhere—if governments have the courage to change the rules.”
Happy New Year to all my followers! Hope 2026 brings good news and peace to residents all over the 🌎! 🎉
Sending you and your family holiday wishes 🎉🎊
In your IE/Systems/OR department, do PhD students usually teach an undergrad course (e.g., Linear Algebra or Engineering Econ.) after they've completed their own coursework? I remember doing that myself (for 3 semesters) as a PhD student and learning a significant amount from that experience.
Good to read that. A couple of years ago the lines were long. I saw your post on LinkedIn; you have many students presenting: my best wishes to them all.
No, I'm not attending this year, but our student is presenting our research on digital twins.
Hope you have a terrific time in Atlanta at @informs.bsky.social 2025!
Congrats to Dr. Elmagrabhy and all the other newly elected members of the board. My very best wishes to them!
Truly excited about teaching a course on Markov Decision Processes #MDPs after a gap of 8 years. #Gratitude to many for making this happen. Am making the notes from the first module publicly available here (comments welcome):

Please join us tomorrow for a timely panel & discussion on #supplychains & #vulnerabilities, thanks to The Democracy Forum, Lord Bruce & @humphreyhawksley.bsky.social www.youtube.com/watch?v=oyqP... @isenbergumass.bsky.social @umassamherst.bsky.social @informs.bsky.social @theorsociety.bsky.social
Will have to disagree a little here and *open to discussion*: Is this really something that a human brain can't catch? I know productivity is a good thing, yet uploading unpublished research into AI means it can get into databases. Plus, I'm repeatedly being told readers like my chatty Indian tone 😂
New addition to website optimization4all.com devoted to operations research, a repository for freely available material on #ORMS. Here is our latest case study w/ codes included for airline revenue management: airline-revenue-managment-or.streamlit.app Detailed write up: github.com/adhikaripraj...
