Separating cover inequalities of maximum depth is not too difficult! If interested, please have a look at our brand new paper with Stefano Coniglio and Daniele Catanzaro

Our new paper with Stefano Coniglio Fabio Furini has been accepted to Mathematical Programming.
We study submodular maximization problems in which a concave utility function is composed with a set-union operator.

It was fantastic to spend the week at the University of Southampton for the #NATCOR course on combinatorial optimisation 😊 One particular highlight was Stefano Coniglio’s talk entitled “integer programming and norm minimisation for data science” #research #math #math ematics #DataScience
How to solve discrete problems that maximize a composition of a concave function with a set-union operator?
With Stefano Coniglio & Fabio Furini we propose a double decomposition: outer approximation combined with #Benders

2021 can come now, but I wish 2021 to bring us many more opportunities to share Tiramisu with our Italian friends, Claudia Archetti Claudia D'Ambrosio Fabio Furini Stefano Coniglio and many more!
Happy new year to all our #orms Twitter friends around the world!
I had a pleasure to stay at Università degli Studi di Brescia visiting D. Manerba and R. Mansini & give a seminar on “Last mile delivery with autonomous robots”.
Great research interactions and social activities, and Stefano Coniglio from UniBg (as a nice surprise!) who joined us for dinner
We started our first day at La Sapienza with a seminar talk of Martin Schmidt on bilevel optimization under uncertainty.
Followed by espresso and Crostata al pistacchio at Ciamei and a walk to Coloseum…
