The first one is aimed to get the aggregated problem as simple as possible. In the second one the iterative correction of the aggregated problem decomposes into independent smaller subproblems. Under the third type of aggregation, applied to the block/separable problems, both aggregated problem and the correction procedure results in the small independent subproblems.  Ключевые слова decomposition, iterative aggregation, block-separable problems
