Metodi didattici

Theoretical lectures and numerical exercises. Recorded lectures will be available upon request.

Seminar given by invited speakers give an insight on impact and applications of the design methodologies introduced in the course.

Modalità di verifica e valutazione dell'apprendimento

Written exercise to test the ability to solve new design problems by applications of the methodologies explained in the course.

The oral exam will immediately follow the written part and will check the ability of the student to elaborate the demonstrations of the theorems and the explain motivations and reasoning in support of network design methodologies. 

The highest scores will require, in addition to correctness, appropriate reporting and good speech organization.
