Computational Complexity of Constraint Satisfaction Problems

This talk is an introduction to techniques to determine the computational complexity of constraint satisfaction problems. The central concept here is the notion of a *polymorphism* of a set of constraints. Polymorphisms can be used to translate questions about computational complexity into questions of fundamental importance in universal algebra. I will first give an overview over recent breakthrough results on constraint satisfaction over finite domains based on this translation. Then I give an introduction on how to generalize those techniques from finite to infinite domain constraint satisfaction, and present applications in temporal reasoning.
