Detailed Description

Branching object for Orbital branching.

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

Member Function Documentation

CbcOrbitalBranchingObject& CbcOrbitalBranchingObject::operator= ( const CbcOrbitalBranchingObject rhs  ) 

Assignment operator.

Reimplemented from CbcBranchingObject.

virtual CbcBranchingObject* CbcOrbitalBranchingObject::clone (  )  const [virtual]

Clone.

Implements CbcBranchingObject.

virtual double CbcOrbitalBranchingObject::branch (  )  [virtual]

Does next branch and updates state.

Implements CbcBranchingObject.

virtual void CbcOrbitalBranchingObject::fix ( OsiSolverInterface solver,
double *  lower,
double *  upper,
int  branchState 
) const [virtual]

Update bounds in solver as in 'branch' and update given bounds.

branchState is -1 for 'down' +1 for 'up'

Reimplemented from CbcBranchingObject.

virtual void CbcOrbitalBranchingObject::previousBranch (  )  [inline, virtual]

Reset every information so that the branching object appears to point to the previous child.

This method does not need to modify anything in any solver.

Reimplemented from CbcBranchingObject.

Definition at line 318 of file CbcSymmetry.hpp.

virtual void CbcOrbitalBranchingObject::print (  )  [virtual]

Print something about branch - only if log level high.

virtual CbcBranchObjType CbcOrbitalBranchingObject::type (  )  const [inline, virtual]

Return the type (an integer identifier) of this.

Implements CbcBranchingObject.

Definition at line 328 of file CbcSymmetry.hpp.

virtual int CbcOrbitalBranchingObject::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.

virtual CbcRangeCompare CbcOrbitalBranchingObject::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.
