 finding a graph partitioning where each group contains the same sum of
 weights, and the sum of the cut edges is minimal (_Find optimal decomposition_). As final step
 the decomposition can be post-process further more to be for optimal, based on factors not considered by the optimization process, like merging vertex, or merging sub-sub-domain, to create bigger sub-domains.
