Complete Distributed Search Algorithm for Cyclic Factor Graphs

Toshihiro Matsui, Hiroshi Matsuo

Abstract

Distributed Constraint Optimization Problems (DCOPs) have been studied as fundamental problems in multiagent systems. The Max-Sum algorithm has been proposed as a solution method for DCOPs. The algorithm is based on factor graphs that consist of two types of nodes for variables and functions. While the Max-Sum is an exact method for acyclic factor-graphs, in the case that the factor graph contains cycles, it is an inexact method that may not converge. In this study, we propose a method that decomposes the cycles based on crossedged pseudo-trees on factor-graphs. We also present a basic scheme of distributed search algorithms that generalizes complete search algorithms on the constraint graphs and Max-Sum algorithm.
