*Título: "**The Discrete Art of Districting*"

*Resumen: *

Territory design problems involve basically partitioning decisions. Given a set of basic geographical areas, the idea is to find a partition of these into groups or districts in such a way that specific planning requirements are met. These requirements depend naturally on the specific application. Districting problems are motivated by very different applications, such as political districting, sales and service territory design, school districting, design of territories for waste collection, to name a few. Throughout the years, many ideas for tackling these very difficult discrete optimization problems have been successfully developed.

In this talk, we will go through some of the most representative models and features, highligthing particular properties and successfull ideas for efficient algorithmic development. Special emphasis will be given to the computational issues and how particular problem structures and properties can be adequately exploited for efficient algorithmic design. The last part of the talk will include a discussion of current research trends on this fascinating class of discrete optimization problems.
