Acknowledgments
I wish to thank Dr. Marieke Huisman for leading me during this thesis; her rigor
and endeavor in every undertaken activity is worthy of admiration. Thanks
to Dr. Willem Visser for inviting me to NASA Ames and discussing topics on
model checking and symbolic methods, also thanks to Dr. Corina Pasareanu with
whom I had fruitful discussions on automatic loop-invariant generation. Many
thanks to Dr. Juan-Francisco D´ıaz-Fr´ıas who first introduced me to research; I
will always remember pleasantly the time spent in the AVISPA team. Finally,
thanks to Dr. Guy Cousineau who gave me the opportunity of starting studies
in France, and thanks to Karina Olmos for reading carefully the previous of this
thesis.
