My main research interest has been the analysis and development of solution approaches for large-scale structured optimization problems, with emphasis on (re)formulation techniques to expose and exploit valuable structural properties of the problems at the interface between continuous and combinatorial optimization. I'm also interested in the numerical analisys, computer science and artificial intelligence / machine learning issues arising within these solution approaches and, vice-versa, in the use of mathematical programming techniques in these disciplines.
I always try to combine three different aspects: methodology,
applications and implementation. This is necessary, in that the
development of a single general solution method may result in improved
performances in several different applications. For instance, the theoretical
results of
[A7,
A14,
A25,
A35] have applications in such diverse
fields as network optimization
[A5,
A9],
scheduling problems for electrical generators
[C1,
C2,
C4,
A10,
A21]
or vehicles and crews
[N1,
A23], and Max-Cut problems
[A13]. On the other hand, investigation
on a specific application often motivates novel methodological developments;
this has been the case e.g. for the results in
[A17], which have been originally
motivated by the study of scheduling problems in electrical power
production, but that have later found very different applications
[A18,
C5]. Finally, the significance of
any methodological or applicative contribution can be vastly increased if
efficient and well-engineered software implementing the idea is made
available to potentially interested users in the academia and in
industry. This is especially true for the development of sophisticated
algorithmic schemes, whose implementation is typically far from trivial.
Because of this, I've taken specific care in developing well-engineered
and easy-to-use software packages, which have been made available under
different open source licenses. I lead the implementation effort for 6
main software projects, for a total of 13 software packages, which can be
downloaded from http://www.di.unipi.it/optimize/Software/; these represent a nontrivial fraction of all open source
optimization projects ever developed in Italy. For the same reasons I
also developed, collected and made available at http://www.di.unipi.it/optimize/Data/ over 20 different data sets for more than 4 different classes of
optimization problems (the site is in the top 10 Google hits for the
keyword "multicommodity" since several years).
I like in particular to thread across boundaries of different fields
such as numerical analysis, diverse aspects of mathematical
programming, and computer science. For instance, applying nonlinear
techniques to discrete problems [A1,
A5,
A10,
A13,
A15,
A18,
A23,
A30] and vice-versa
[A16,
A17,
B4], investigating numerical analysis
aspects of optimization algorithms
[A6,
A12] and vice-versa
[A19], applying parallel programming
techniques to the solution of optimization poblems
[A9,
B2], or working in the interplay
between mathematical programming, artificial intelligence and machine learning
[B5,
B6]. This is due to my profound belief
in the need of continuously adapting the research tools to the needs of the
problem at hand, if necessary challenging the limits and the fences
that — often surreptitiously — divide disciplines.
From the methodological standpoint, the main algorithmic techniques that I have investigated are:
convex NonDifferentiable Optimization algorithms, with a specific focus on Lagrangian relaxation;
enumerative algorithms for nonlinear mixed-integer programs.
From the applicative standpoint, I have mainly investigated the following problems:
When appropriate, I have also investigated other problems and methodologies. A more in-depth description of my research can be found at www.di.unipi.it/~frangio/research.html.

I've been supervisor of 3 Ph.D. Theses:
| Qinghua Zhang | Outer Approximation Algorithms for DC Programs and Beyond | 2008 | Doctorate in Mathematics, University of Pisa | |
| Fausto Pascali | Chance Constrained Network Design | 2009 | Doctorate in Mathematics for Economy, University of Pisa | |
| Luis Pèrez Sànchez | Artificial Intelligence Techniques for Automatic Reformulation and Solution of Structured Mathematical Models | 2010 | Doctorate in Computer Science, University of Pisa |
I've been supervisor of 6 Master Theses in Computer Science and 1 Master Thesis in Mathematics at the University of Pisa, plus a Master Thesis Electrical Engineering at the University of Bari (that won the AIRO Prize in 2007) and a Master Thesis in Mathematics at the University of Insubria. I have supervised 12 dissertations for the undergrad diploma in Computer Science of the university of Pisa; one of them won the AIRO Prize in 2006. I've collaborated to the supervision of several other Ph.D. and Master Theses. I've been external advisor for four Ph.D. Theses abroad (Canada, Spain, Portugal, and France).
