Nov 29, 2018 at 15:01 comment added how_to_seat @ReneBt, I was only asking about a single swap but multiple swaps would be ideal.

Nov 29, 2018 at 2:22 comment added Glen_b It is because of its connection to experimental designs that I see this question as within our range of topics on CV, though arguably it might also count as an optimization problem on which AI techniques are sometimes applied; however, there are multiple questions on this type of problem on math.SE (if it's on topic here it should stay; if it's not that's probably the best place for it)
