The task of building mathematical models that represent real-world problems and using existing tools for solving such models is an ubiquitous task in computer science. Knowledge about such tools and algorithms allows one to weigh up the balance between how precisely we formalize the problem and how tractable the resulting model is.
With an special emphasis on their application to concrete computer science problems, this course will review some of these mathematical models and algorithms. First of all, we will review the basics of (integer) linear and non-linear programming. Then, metaheuristic algorithms will be presented as an alternative to the previous methods for combinatorial optimization problems. Other mathematical elements with strong impact in computer science, such as graphs or computation and use of eigenvalues/vectors, will also be covered throughout the course.

Contents
Eigenvalues and eigenvectors
Basics on linear algebra. Eigenvalues, eigenvectors and their interpretation. Applications to computer science (clustering, graph layout, principal component analysis, page rank,...)
(Integer) Linear Programming
Basics on linear programming. Modelling examples. The simplex algorithm. Duality. Integer programming: branch-and-bound, cuts and branch-and-cut.
Since the goal of the course is to provide the students with the necessary expertise to use different formalisms and tools to solve concrete problems, the teaching methodology will take that into account. Theory classes will always use motivating examples coming from computer science applications, with special emphasis given to practical issues. In these sessions, students will solve simple exercises that will be key ingredients of more complicated algorithms.
In the laboratory sessions the students will become familiar with the systems that will then be used in their course project. In the development of the project the students will be supervised by the instructors.
Evaluation methodology
The final grade of the course will take into account:
A) Practical work: the students, in small groups, will develop a course project. A variety of projects will be suggested by the instructors so that all specializations are represented. The project will amount to solve a concrete problem by using both (non)linear programming techniques and metaheuristics. Grading will be as follows:
