Translations for the pragmatist:
Cost of ith pairing
= 1 for all selected pairings, else 0
= 1 if leg i is in pairing j, else 0
i indexes plane legs, j indexes pairings

2: Even if we reduce number of pairings, still have to be able to solve large MIP problems efficiently (tens of thousands of constraints, hundreds of thousands of variables).
