Combinatorial optimization (find partitions)

A problem arose to solve the problem with a solution that became impracticable. Well, I have a set of 12 elements that represent quantities: $$\Omega = \{16, 132, 135, 135, 136, 138, 138, 139, 301, 334, 355, 361\}$$ I can join elements, get subsets, of this set such that the sum of the elements does […]
