virtual double | branch (OsiSolverInterface *solver=NULL) |
Execute the actions required to branch, as specified by the current state of the branching object, and advance the object's state. | |

use CouenneBranchingObject::variable_ as the first variable to set to 0, and this one as the second | |
int | sign_ |
-1 if object is for xi * xj <= 0 +1 if object is for xi * xj <= 0 0 if object is for xi * xj = 0 (classical) |
Branching on such an object x_1 x_2 = 0 is performed by setting either x_1=0 or x_2=0
