The programme for our https://t.co/eyFQouiUXl workshop is out: Register now for participation! #scipopt #orms

This year SCIP is about to turn 20! Join us for a scientific birthday workshop with invited speakers @meurevine @dominiqs81 and many talks on computational mixed integer optimization: November 4th, @ZuseInstitute Berlin, https://t.co/eyFQouin7N #scipopt #orms

[Ambros Gleixner @ambrosgleixner]

An early holiday present: The SCIP Optimization Suite 8.0 is out! Improved performance for linear and nonconvex mixed-integer problems and many new features in the core and SCIP's extensions. Find details in https://t.co/8LHsvGomAb and at https://t.co/JidjyGUCG1 ! #orms

Very happy to hear that I am one of the lucky awardees of an @NWONieuws OC-M grant! Looking forward to hiring my first PhD student to carry out research on finding and exploiting network matrices in mixed-integer programs @UTwente!

The #ipco2021 local committee has just set a very high bar for conferences... we have a beach! :) @swati1729 @mohitsinghr @SantanuSDey

[Matthias Walter @mwaltermath]

@mohitsinghr @swati1729 @GeorgiaTechISyE @isyeopt @69alodi @oktaygunluk Any news on whether we'll actually meet in person, or when this might be decided?

Spannender Artikel über spannende #Mathematik: Wir brauchen eine #Wahl-rechtsreform, endlich nach der #Bundestagswahl 2021. Lasst uns moderne mathematische Optimierungsmethoden nutzen, um Wahlkreise klüger und gerechter zu schneiden. @SGoderbauer https://t.co/HiuFj4LBOo

Just finished the paper with @MarijeSiemann about her MSc thesis at @UTwente with a first polyhedral study on the traveling tournament problem where we lifted model inequalities and found some new ones. Results are easy to parse, but proofs are technical: https://t.co/OqCYOu34g8

Polishing the plots for my #IPCO2021 submission.

@MarijeSiemann @miketrick Well deserved Master of Applied Math!

[Matthias Walter @mwaltermath]

@rybekci You need to become a full professor - before, all positions are temporary ones.

[Matthias Walter @mwaltermath]

I just signed the contract for my first permanent position - would have been impossible in German academia!

[Matthias Walter @mwaltermath]

@ERodriguezHeck Thank you!

[Matthias Walter @mwaltermath]

The conference version of our paper https://t.co/G7nVAdkvq9 on persistencies just got accepted for #ipco2020. Great work @ERodriguezHeck, @swltg and Karl Stickler!

@schmaidt How about the Optima interview of Bob Bixby https://t.co/wMCC8qRnz1?
