Member Function Documentation

CbcLongCliqueBranchingObject& CbcLongCliqueBranchingObject::operator= ( const CbcLongCliqueBranchingObject rhs)
virtual CbcBranchingObject* CbcLongCliqueBranchingObject::clone ( ) const
virtual

Clone.

Implements CbcBranchingObject.

virtual double CbcLongCliqueBranchingObject::branch ( )
virtual

Does next branch and updates state.

Implements CbcBranchingObject.

virtual void CbcLongCliqueBranchingObject::print ( )
virtual

Print something about branch - only if log level high.

virtual CbcBranchObjType CbcLongCliqueBranchingObject::type ( ) const
inlinevirtual

Return the type (an integer identifier) of this.

Implements CbcBranchingObject.

Definition at line 269 of file CbcClique.hpp.

virtual int CbcLongCliqueBranchingObject::compareOriginalObject ( const CbcBranchingObject brObj) const
virtual

Compare the original object of this with the original object of brObj.

Assumes that there is an ordering of the original objects. This method should be invoked only if this and brObj are of the same type. Return negative/0/positive depending on whether this is smaller/same/larger than the argument.

Reimplemented from CbcBranchingObject.

virtual CbcRangeCompare CbcLongCliqueBranchingObject::compareBranchingObject ( const CbcBranchingObject brObj,
const bool  replaceIfOverlap = false 
)
virtual

Compare the this with brObj.

this and brObj must be os the same type and must have the same original object, but they may have different feasible regions. Return the appropriate CbcRangeCompare value (first argument being the sub/superset if that's the case). In case of overlap (and if replaceIfOverlap is true) replace the current branching object with one whose feasible region is the overlap.

Implements CbcBranchingObject.
