Member Function Documentation

virtual OsiObject* OsiLotsize::clone ( ) const
virtual

Clone.

Implements OsiObject.

OsiLotsize& OsiLotsize::operator= ( const OsiLotsize rhs)
virtual double OsiLotsize::infeasibility ( const OsiBranchingInformation info,
int &  whichWay 
) const
virtual

Infeasibility - large is 0.5.

Implements OsiObject.

virtual double OsiLotsize::feasibleRegion ( OsiSolverInterface solver,
const OsiBranchingInformation info 
) const
virtual

Set bounds to contain the current solution.

More precisely, for the variable associated with this object, take the value given in the current solution, force it within the current bounds if required, then set the bounds to fix the variable at the integer nearest the solution value. Returns amount it had to move variable.

Implements OsiObject.

virtual OsiBranchingObject* OsiLotsize::createBranch ( OsiSolverInterface solver,
const OsiBranchingInformation info,
int  way 
) const
virtual

Creates a branching object.

The preferred direction is set by way, 0 for down, 1 for up.

Reimplemented from OsiObject.

void OsiLotsize::setColumnNumber ( int  value)
inline

Set solver column number.

Definition at line 874 of file OsiBranchingObject.hpp.

virtual int OsiLotsize::columnNumber ( ) const
virtual

Column number if single column object -1 otherwise, so returns >= 0 Used by heuristics.

Reimplemented from OsiObject.

virtual void OsiLotsize::resetBounds ( const OsiSolverInterface solver)
virtual

Reset original upper and lower bound values from the solver.

Handy for updating bounds held in this object after bounds held in the solver have been tightened.

Reimplemented from OsiObject.

bool OsiLotsize::findRange ( double  value,
double  integerTolerance 
) const

Finds range of interest so value is feasible in range range_ or infeasible between hi[range_] and lo[range_+1].

Returns true if feasible.

virtual void OsiLotsize::floorCeiling ( double &  floorLotsize,
double &  ceilingLotsize,
double  value,
double  tolerance 
) const
virtual

Returns floor and ceiling.

double OsiLotsize::originalLowerBound ( ) const
inline

Original bounds.

Definition at line 900 of file OsiBranchingObject.hpp.

double OsiLotsize::originalUpperBound ( ) const
inline

Definition at line 902 of file OsiBranchingObject.hpp.

int OsiLotsize::rangeType ( ) const
inline

Type - 1 points, 2 ranges.

Definition at line 905 of file OsiBranchingObject.hpp.

int OsiLotsize::numberRanges ( ) const
inline

Number of points.

Definition at line 908 of file OsiBranchingObject.hpp.

double* OsiLotsize::bound ( ) const
inline

Ranges.

Definition at line 911 of file OsiBranchingObject.hpp.

virtual void OsiLotsize::resetSequenceEtc ( int  numberColumns,
const int *  originalColumns 
)
virtual

Change column numbers after preprocessing.

Reimplemented from OsiObject.

virtual double OsiLotsize::upEstimate ( ) const
virtual

Return "up" estimate (default 1.0e-5)

Reimplemented from OsiObject.

virtual double OsiLotsize::downEstimate ( ) const
virtual

Return "down" estimate (default 1.0e-5)

Reimplemented from OsiObject.

virtual bool OsiLotsize::canHandleShadowPrices ( ) const
inlinevirtual

Return true if knows how to deal with Pseudo Shadow Prices.

Reimplemented from OsiObject.

Definition at line 922 of file OsiBranchingObject.hpp.

virtual bool OsiLotsize::canDoHeuristics ( ) const
inlinevirtual

Return true if object can take part in normal heuristics.

Reimplemented from OsiObject.
