Which variable (top bit if upper bound changing)
const double * newBounds() const
CbcNodeInfo * parent() const
Parent of this.
int numberChangedBounds_
Number of bound changes.
Holds information for recreating a subproblem by incremental change from the parent.
int * variables_
Which variable (top bit if upper bound changing)
const CoinWarmStartDiff * basisDiff() const
Basis diff information.
CoinWarmStartDiff * basisDiff_
Basis diff information.
virtual CbcNodeInfo * buildRowBasis(CoinWarmStartBasis &basis) const
Builds up row basis backwards (until original model).
OsiRowCut augmented with bookkeeping.
Information required while the node is live.
virtual void applyToModel(CbcModel *model, CoinWarmStartBasis *&basis, CbcCountRowCut **addCuts, int ¤tNumberCuts) const
Modify model according to information at node.
const CbcNode * owner() const
Information required to recreate the subproblem at this node.
virtual CbcNodeInfo * clone() const
Clone.
int numberChangedBounds() const
Number of bound changes.
virtual int applyBounds(int iColumn, double &lower, double &upper, int force)
Just apply bounds to one variable - force means overwrite by lower,upper (1=>infeasible) ...
Simple Branch and bound class.
