Abstract

We prove exponential lower bounds on the running time of many algorithms for Constraint Satisfaction, by giving a simple family of instances on which they always take exponential time. Although similar lower bounds for most of these algorithms have been shown before, we provide a uniform treatment which illustrates a powerful general approach and has stronger implications for the practice of algorithm design.
