## Update II [🇷 for BE/BA]

After re-re-re-re-reading the documentation for optim, I think it can be forced to look for either a minimum (default) or for a maximum if need be through the control argument or, more simply, the objective function should be handled for a minimum by putting a minus sign on the return of Obj.F12...
... but even so the estimates are still somewhat off.

Pass or fail!
