[Coin-discuss] SBB getObjValue max problem

[Matthew Galati]

When solving a max problem with SBB and getting back the objective
value, it looks to me like the signs are switched. I presume,
internally,  that SBB flips the objective and solves it as a min - but
it doesn't seem to switch back the final objective value.

siBB->setObjSense(-1);
SbbModel sbb(*siBB);
sbb.branchAndBound();
correctObj = -1 * sbb.getObjValue();
