Learning objectives
Students will study, design and analyze algorithms and data structures for the efficient solution of many different problems, highlighting the applicative contests in which the considered algorithms and data structures can be successfully employed. This course deepens and extends the algorithmic notions given in Algoritmi e Strutture dati 1.
Knowledge and understanding:
The main objective of this course is to give a deeper insight to the most important and useful algorithms and data structures.
Applying knowledge and understanding:
Students will be able to design and analyze algorithms fo medium-difficult problems.
Making judgements:
Ability to judge the quality of a software solution by means of efficency and possibly reuse. Students will be able to appreciate the consequence of their algorithmic results.
Communication skills:
Ability to motivate and explain efficient programming concepts, relevant alternatives and decision recommendations, even to nonprofessional audience. Students will be able to highlight the technological consequences of their theoretical studies.
Learning skills: Students can keep up-to-date with the latest developments in algorithmics by consulting scientific journals and advanced books. The knowledge acquired in the course will allow the students to attend both master and specialistic classes.

Class
Assessment methods and criteria
Final oral examination based on the topics discussed in class. Project development and/or seminar discussion in algorithms, data structures and complexity take place. The purpose is to test the algorithmic design skills of the students. Students can get the minimum grade by showing a sufficient knowledge of the tools for the analysis and synthesis of the algorithms discussed in class.
