Learning objectives
The goal of the course is to familiarize students with algorithms, data structures and with the techniques needed for analyzing their efficiency.
Knowledge and understanding:
The main objective of this course is to acquire the tools and techniques needed to analyze and design practical algorithmic solutions to elementary real-world problems. This course gives students an in-depth understanding of a wide range of fundamental algorithms and data structures used in developing structured, efficient, reusable, and practical software.
Applying knowledge and understanding:
Students will be able to compare different algorithms for the same task, and predict or guarantee performance for large problems. Students will be able to study the inherent difficulty of the given problem, to model and implement efficient software solutions using appropriately selected algorithms and data structures.

Teaching methods
Class, exercises. Meanwhile (Lab of “Fondamenti di Programmazione B”) some of the most significant data structure are implemented in C++.
Assessment methods and criteria
Written and oral examination. Written examination includes a number of exercises some of which are simple variants of exercises given in class, others are totally new, but can be solved by using the techniques discussed in class.
Students can get the minimum grade by solving the exercises of the first kind.
