Detailed Description

Branching object for Special ordered sets.

Variable_ is the set id number (redundant, as the object also holds a pointer to the set.

clone()

Clone.

Implements CbcBranchingObject.

branch()

virtual double CbcLinkBranchingObject::branch ( )

virtual

Does next branch and updates state.

Implements CbcBranchingObject.

print()

virtual void CbcLinkBranchingObject::print ( )

virtual

Print something about branch - only if log level high.

type()

virtual CbcBranchObjType CbcLinkBranchingObject::type ( ) const

inlinevirtual

Return the type (an integer identifier) of this.

Implements CbcBranchingObject.

compareBranchingObject()

virtual CbcRangeCompare CbcLinkBranchingObject::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.
