protected

SmartPointer to the Journalist.

Definition at line 108 of file CouenneSOSObject.hpp.

◆ doFBBT_

bool Couenne::CouenneSOSObject::doFBBT_

protected

shall we do Feasibility based Bound Tightening (FBBT) at branching?

Definition at line 111 of file CouenneSOSObject.hpp.

◆ doConvCuts_

bool Couenne::CouenneSOSObject::doConvCuts_

protected

shall we add convexification cuts at branching?
