Multi-objective problems have been addressed in the research area of DCOPs recently. For the case of multiple objectives, the objective values are defined as the result of separate evaluation schemes. Applying multi-objectives to pseudo-tree based search is also important to generalize several traditional solvers. Here, we introduce boundaries for the vector of objective values in a solver based on pseudo-trees. Both the bottom-up computation of the partial dynamic-programming and the top-down computation of the tree-search employ the bounded vectors of the objective values. Several operations including aggregation, decomposition and comparison of objective values are extended for the bounded vectors.}, identifier = {06105884}, }
