Research Interests and Publications
My research is mainly concerned with nonlinear optimization. My work has included
- Global Optimization: study of algorithm with theoretical convergence properties and application to different real world problems;
- Semidefinite Programming (SDP): study of optimality conditions for nonlinear programming problems arising as low rank reformulations of linear SDPs, and nonlinear programming based algorithms for solving SDP relaxations of the max cut problem;
- Generalized Nash Equilibrium Problems (GNEPs): theory and algorithms for specific classes like jointly convex GNEPs and Generalized Potential Nash Equilibrium Problems. Application to real world problems as computation offloading in mobile cloud computing.
- Mixed Integer Non Linear Programming: algorithms for convex functions depending on mixed variables
- Hazardous Material Transportation: game theory based models
- Machine learning: optimization based approaches for feature ranking, applications in BCI, and NILM both by Deep Learning and Optimization
You may find an updated list of my publications here (also available on Google Scholar).
New: Marco Sciandrone and I finished the survey Nonlinear Optimization and Support Vector Machines .
Software and Applications
- I partecipated to the optimization of the Italian Volley Tournament schedule for 2016/17 with the Global Optimization Laboratory of the University of Florence. We successfully developed a mixed integer optimization model to solve the complex problem of scheduling the volley torunament. An official post from the Italian Volley League is now available . The schedule has been officially presented in Bologna – a video of the whole event is available (go to minute 27).
- At this link you can find the Branch and Bound algorithm for Standard Quadratic Programming (StQP) described in the paper A new branch-and-bound algorithm for standard quadratic programming problems realized with Giampaolo Liuzzi and Marco Locatelli .
- I took part to the development of the SpeeDP code that can be used through this website.
- I took part to the development of some global optimization algorithms (DFSA, DDFSA, DIRMIN, DIRDFN, DIRECT) part of the DFL library downloadable here.
