Indeed. If this is needed, we'll consider it.

OK, your input is making my motivation to fight with Jonker-Volgenant go
down. I'll see with the other people involved if we still target
Jonger-Volgenant, or if we stick with the hungarian algorithm, in which
case the problem is solved.

It does. Thanks a lot, it is very useful to have expert knowledge
available.
