My main research interest is the analysis, development, implementation and testing of solution approaches for large-scale structured optimization problems at the interface between continuous and combinatorial optimization, with emphasis on (re)formulation techniques to expose and exploit valuable structural properties, and their real-life application in several fields (energy, transportation, telecommunications, ...) I'm also interested in the numerical analysis, computer science, artificial intelligence and 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,
A55] have applications in such diverse
fields as network optimization
[A5,
A9,
A22],
scheduling problems for electrical generators
[C1,
C2,
C4,
A10,
A21,
A56]
or vehicles and crews
[N1,
A23,
A64], 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
[A45,
A43,
A42,
A30,
A18,
C5,
A74]. 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 [A39],
as documented in the corresponding section that
describes the software packages I have contributed to (often with a
leading role), which represent a nontrivial fraction of all open source
optimization projects ever developed in Italy. For the same reasons I also
developed or collected and made available at
https://commalab.di.unipi.it/datasets/
many different data sets for several different classes of optimization
problems, and I have contributed to standard libraries of instances
[A61].
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
[A44,
A47,
A19], applying parallel programming
techniques to the solution of optimization poblems
[A9,
B2], applying optimization techniques to
algorithm design issues [A40,
A65], or working in the interplay
between mathematical programming, artificial intelligence and machine learning
[B5,
B6,
B14,
B15,
A73,
C18,
E1,
A74]. This is due to the realization that
one must continuously adapt ones' 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.

Since 1999 I'm one of the main contributors to the "Lecture Notes in Operations Research" ("Appunti di Ricerca Operativa", in Italian) jointly developed by the members of the CommaLAB of the Department of Computer Science of the University of Pisa. The Lecture notes are constantly improved, and are freely available to the students of several courses (in Computer Science, Mathematics, Engineering, ...) at the University of Pisa. The Lecture Notes can also be, and have been, freely used for courses of other Italian universities. The most recent version of the Lecture Notes can be freely downloaded from the web pages of the relevant Operations Research courses of the University of Pisa.
