@elina_ronnberg @Roghayeh_hz Wohoo! Well done! 🥳

[Elina Rönnberg @elina_ronnberg]

Not every day an OR research project is mentioned on Swedish national radio -- but last week they decided to report on our E-VRP project 😃

[Elina Rönnberg @elina_ronnberg]

Proud to launch the webpage of our research group
"Mathematics and algorithms for intelligent decision-making"

(not all projects and collaborations are there yet, stay tuned for updates)

[Aigerim Saken @AigerimSaken]

Happy to share this preprint of our new paper w/ @emil_j_ , @elina_ronnberg , @sj_maher . We evaluate cut-strengthening techniques for Logic-based Benders’ decomposition

And big first announcement, SCIP is since today midnight a truly open-source project under the Apache 2.0 license

[Emil Karlsson @emil_j_]

@matbesancon @Allen_GoWorld This is amazing! :)

[Elina Rönnberg @elina_ronnberg]

Any of my CP friends looking for a challenge?
We just published a scheduling data set where very similar instances differ a lot in computational time for IBM ILOG CPO. Can you improve?

Originates from the PhD thesis of @emil_j_

[Elina Rönnberg @elina_ronnberg]

Happy to kick off the #ELLIITFocusPeriod on Hybrid AI by meeting the scholars visiting us in the first two weeks of this four-week program at @liu_universitet. Organisation by @FredrikHeintz, Anders Hansson, Tove Kvarnström, and I 😃

[Elina Rönnberg @elina_ronnberg]

I have an open position for a PhD student in discrete optimisation:
Improve mathematical models and methods for decision-making under uncertainty

Final day of #EURO2022 and PhD student @AigerimSaken is doing a great job presenting our + @sj_maher + @emil_j_ work on cut-strengthening techniques for Logic-based Benders Decomposition. Thanks @k_conference for this time and to all people involved in making happen!

[Emil Karlsson @emil_j_]

@elina_ronnberg @ORMS_Elsevier @k_conference Nice work we did and good timing :) Have a good time at EURO!

[Elina Rönnberg @elina_ronnberg]

While preparing my #EURO2022 presentation, the final version of our @ORMS_Elsevier paper that I'm going to present appears online in Computers & Operations research
https://t.co/1wYhTlWfgm
Looking forward to the @k_conference!

[Elina Rönnberg @elina_ronnberg]

Perfect 1-year celebration of his PhD defence: Last week we got the last paper of his PhD thesis accepted in Computers & Operations Research -- today @emil_j_ gets to present the work at Stockholm Optimization days 🥳

[Emil Karlsson @emil_j_]

@elina_ronnberg Thank you :) Agree, an excellent 1 year celebration!

[Emil Karlsson @emil_j_]

Always happy to see my (former) PhD supervisor @elina_ronnberg in action! Great presentation and research!

[Thiago Serra (@thserra.bsky.social) @thserra]

The next plenary at Stockholm Optimization Days is by @elina_ronnberg on a neat approach for using Large Neighborhood Search in column generation with the production of promising columns involving set covering, packing, and partitioning constraints #orms

[Elina Rönnberg @elina_ronnberg]

Great to attend the first in-person conference in a long time -- and even better to do so in Stockholm with lots of interesting people attending.

Thanks @JanKronqvist for this superb initiative!

[Jan Kronqvist @JanKronqvist]

Stockholm Optimization Days are off to a great start with plenary talks by Ann-Brith Strömberg and Ambros Gleixner

[Jan Kronqvist @JanKronqvist]

Great opportunity to join my research group at KTH as a Postdoc and work on a project in the intersection of mixed-integer optimization and AI/ML @KTHuniversity #optimization #ML #AI https://t.co/fm1riuto0v
