On bounded occurrence constraint satisfaction

Download www.ti.inf.ethz.ch

An approximation algorithm for a constraint satisfaction problem is said to be nontrivial if its performance ratio is strictly superior to the expected performance of the algorithm which simply chooses a random assignment. We prove that any constraint satisfaction problem where each variable appears a bounded number of times admits a nontrivial polynomial time approximation algorithm.
