# Activities

My research activities focuses on Computational Methods based on Mathematical Optimization and Constraint Programming to solve challenging (i.e., NP-hard) problems.

I maintain Spaghetti Optimization which is a blog related to my research interests.

From October, 1st, 2013, I collaborate with AntOptima, where we developed several industrial solutions based on Mathematical Optimization algorithms.

From January, 1st, 2011, to September, 30th, 2013, I was involved on a joint research project
with MAIOR and ATM about *Disruption Management in Public Transportation Systems*.
In a previous project, we worked on *Bus Drivers Scheduling* related problems,
in particular we solved the Resource Shortest Path Problems with Super Additive Cost Functions.

In 2010, I have translated in Italian the following textbook:

- B. Korte, J. Vygen, Combinatorial Optimization - Theory and Algorithms, Springer. 670 pages. ISBN: 978-88-470-1522-7.
