Define a cut branching class.
int preferredWay() const
If -1 down always chosen first, +1 up always, 0 normal.
Definition: CbcObject.hpp:258
Abstract Base Class for describing an interface to a solver.
Define a branch class that branches so that it is only satsified if all members have different values...
double infeasibility() const
Return infeasibility.
virtual CbcBranchingObject * createCbcBranch(OsiSolverInterface *solver, const OsiBranchingInformation *info, int way)
Creates a branching object.
CbcModel * model() const
Return model.
Definition: CbcObject.hpp:252
Abstract branching object base class Now just difference with OsiBranchingObject. ...
CbcBranchAllDifferent & operator=(const CbcBranchAllDifferent &rhs)
virtual CbcObject * clone() const
Clone.
int * which_
Which variables.
Simple Branch and bound class.
