# 69441 - OPTIMIZATION MODELS AND ALGORITHMS M

## Learning outcomes

Integer Programming is a very powerful tool for modeling combinatorial optimization problems arising in many branches of engineering, industry and resource allocation. The first part of this course covers the modeling aspects of the field, providing the tools for constructing effective mathematical models, i.e., models that can be solved in practice. The second part is devoted to the algorithmic aspects: basic algorithms are reviewed and more sophisticated ones, useful for those models characterized by a large number of variables and/or constraints, are presented in detail. Finally, the third part of discusses real-world applications. Note: This course is taken from the Second-cycle Degree in Ingegneria Gestionale.

## Course contents

Requirements: a good knowledge of the basics of set theory, and vectorial and matricial calculus is required.

The course is given in English: slides and exercises are in English. The exam must be taken in English.

The course focuses on optimization problems arising in decision making, with particular emphasis on Combinatorial Optimization problems. The first goal of the course is to teach the theory of Linear Programming and Integer Linear Programming, and how to formulate mathematical models for optimization problems belonging to these classes. The classical Integer Linear Programming problems are also presented. The second goal is to teach exact and heuristic algorithms to solve these problems. In addition, the basics of computational complexity of problems and algorithms are introduced, and graph theory concepts and the classical problems modelled on graphs are described. The last part of the course is dedicated to practical applications: more complex real-world optimization problems are presented and the use of optimization tools is shown.
