Title: Discrepancy and Combinatorial Optimization
Abstract: Discrepancy is a combinatorial property that is closely related to how well a fractional solution to a linear program can be rounded to an integral one. We will explore various techniques in discrepancy theory, and their applications to basic problems in combinatorial optimization. Some of the topics that we will cover include, rounding techniques based on random walks and linear algebra, Steinitz lemma and its use in integer programming, tools from convex geometry to show existence of and find integer points in convex bodies.

Title: An Introduction to Semidefinite Programming for Combinatorial Optimization
Abstract: Semidefinite programming (SDP) is a powerful modeling technique that extends both linear and secondorder cone programming. In this tutorial, we discuss the basics of SDP, including applications, duality, algorithms, and software. We'll also cover various SDP relaxation techniques for combinatorial optimization problems such as MaxCut and maxiumum stable set, which are classical "success stories" in this area. Finally, we'll explore the boundary of current research, especially in the area of mixedinteger nonlinear programming.

Title: Sums of Squares in Polynomial Optimization
Abstract: Polynomials offer an extremely general strong tool to encode optimization problems, both discrete and continuous. However polynomial optimization is in general hard, and for a long time it has been confined mostly to the realm of theoretical real algebraic geometry. The advent of efficient semidefinite programming a couple of decades ago, transformed what was a purely theoretical pursuit into a practical endeavor, and gave rise the development of general tools for approximating polynomial optimization problems. The most common of these approaches is perhaps the sum of squares approach, that relies on certifying nonnegativity of polynomials by writing them as sums of squares of other polynomials, and that allows anyone to quickly obtain bounds for polynomial optimization problems. In these lectures, a quick overview of the theoretical foundations for these techniques will be given, as well as an overview of how can they be applied to bound a range of problems from diverse areas. Finally we will review some recent and ongoing developments in the field.

João Gouveia obtained his PhD from University of Washington in 2011, and has since been in the Department of Mathematics at the University of Coimbra, where he is currently an associate professor. His main interests lie at the intersection of optimization, algebraic geometry and convex geometry, but he is also usually involved in several applied industrial projects.
