Member Function Documentation

bestBranch()

virtual int CbcBranchUserDecision::bestBranch ( CbcBranchingObject **  objects, int  numberObjects, int  numberUnsatisfied, double *  changeUp, int *  numberInfeasibilitiesUp, double *  changeDown, int *  numberInfeasibilitiesDown, double  objectiveValue  )

virtual

Compare N branching objects.

Return index of best and sets way of branching in chosen object.

This routine is used only after strong branching. This is reccommended version as it can be more sophisticated

betterBranch()

virtual int CbcBranchUserDecision::betterBranch ( CbcBranchingObject *  thisOne, CbcBranchingObject *  bestSoFar, double  changeUp, int  numberInfeasibilitiesUp, double  changeDown, int  numberInfeasibilitiesDown  )

virtual

Returns nonzero if branching on first object is "better" than on second (if second NULL first wins).

This is only used after strong branching. The initial selection is done by infeasibility() for each CbcObject return code +1 for up branch preferred, -1 for down

clone()

virtual CbcBranchDecision* CbcBranchUserDecision::clone ( ) const

virtual

Clone.

initialize()

virtual void CbcBranchUserDecision::initialize ( CbcModel *  model )

virtual

Initialize i.e. before start of choosing at a node.

operator=()

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

private

Illegal Assignment operator.
