On the basis of what has been developed both in the theoretical and in the applicative parts of the book, this final chapter tries to draw some conclusions on the characteristics of all the techniques discussed. Thus, the different topics in optimization theory are recalled and their scope summarized. Some considerations on how to choose the proper optimization set-up depending on the type and the complexity of the optimization problem at hand are discussed. The leitmotiv of this chapter is the question posed at its beginning “what would be the best thing do to?” when tackling an optimization problem. Aware that there is no final and unique answer to this question, we believe that some theoretical knowledge in the field of optimization and some ideas on how it can be put into practice should form a good basis to start from when making your own decisions. That’s what the book intended to do and hopefully managed to. Now it’s time for the reader to move his steps forward and ideally broaden the second part of this book with his own applications!
