3 Marc Pujol Jesús Cerquides Pedro Meseguer Juan A. Rodríguez-Aguilar 2011 Workshop on Distributed Constraint Reasoning at IJCAI 2011 Barcelona 99-111 17/07/2011 In this paper we focus on solving DCOPs in computationally demanding scenarios. GDL optimally solves DCOPs, but requires exponentially large cost functions, being impractical in such settings. Function filtering is a technique that reduces the size of cost functions. We improve the effectiveness of function filtering to reduce the amount of resources required to optimally solve DCOPs. As a result, we enlarge the range of problems solvable by algorithms employing function filtering.
