Course Content
 Review of computational complexity and intractability. Optimization problems. Approximation algorithms.
 Algorithmic techniques: greedy.
 Algorithmic techniques: local search and dynamic programming.
 Linear programming techniques: rounding and primaldual methods
 Polynomial Time Approximation Schemes (PTAS) and Fully Polynomial Time Approximation Schemes (FPTAS).
 Negative approximation results and gap technique. Complexity classes for optimization problems and their inclusions
Learning Outcomes (Dublin Descriptors)
On successful completion of this course, the student should

Acquire knowledge of advanced algorithmic techniques for NPHard optimization problems. In particular, the student will
have mastery command of main algorithmic (approximation) techniques like greedy, local search, dynamic programming, linear programming: rounding and primaldual methods, Polynomial Time Approximation Schemes (PTAS) and Fully Polynomial Time Approximation Schemes (FPTAS). Moreover the student will acquire knowledge on negative approximation results and gap technique, and therefore on the complexity classes for optimization problems.

Acquire the ability of abstracting models and formal algorithmic problems from real computational problems, understanding the degree of approximability and designing efficient algorithmic solutions.

Acquire autonomy in individuating, formalizing and understanding the degree of approximability of real computational problems and identify independently their most efficient solutions.

Being able to understand complex algorithms solutions and to formal proving performances of their algorithmic solutions for complex computational problems.

The course aims to develop in graduate students competencies and abilities necessary in their future studies and/or works, especially with respect to doctoral studies and in general to any research activity on algorithmic topics.
Prerequisites and Learning Activities
KNOWLEDGE: fundamentals of programming, discrete mathematics, algorithms and data structures, computer architectures, reading and understanding of the English language
SKILLS: ability to integrate classroom and homework study, ability to interact with the teacher during the class for originating discussion.
Assessment Methods and Criteria
Final written examination.
