## Member Function Documentation

void OsiColCut::setLbs | ( | int | nElements,
|  | const int * | colIndices,
|  | const double * | lbElements
| ) |  |
| inline

Set column lower bounds.

Definition at line 155 of file OsiColCut.hpp.

void OsiColCut::setLbs | ( | const CoinPackedVector & | lbs | ) |
| inline

Set column lower bounds from a packed vector.

Definition at line 171 of file OsiColCut.hpp.

void OsiColCut::setUbs | ( | int | nElements,
|  | const int * | colIndices,
|  | const double * | ubElements
| ) |  |
| inline

Set column upper bounds.

Definition at line 163 of file OsiColCut.hpp.

void OsiColCut::setUbs | ( | const CoinPackedVector & | ubs | ) |
| inline

Set column upper bounds from a packed vector.

Definition at line 176 of file OsiColCut.hpp.

const CoinPackedVector & OsiColCut::lbs | ( |  | ) | const
| inline

Get column lower bounds.

Definition at line 184 of file OsiColCut.hpp.

const CoinPackedVector & OsiColCut::ubs | ( |  | ) | const
| inline

Get column upper bounds.

Definition at line 189 of file OsiColCut.hpp.

bool OsiColCut::operator== | ( | const OsiColCut & | rhs | ) | const
| inline virtual

    equal - true if lower bounds, upper bounds,

and OsiCut are equal.

Definition at line 197 of file OsiColCut.hpp.

bool OsiColCut::operator!= | ( | const OsiColCut & | rhs | ) | const
| inline virtual

not equal

Definition at line 209 of file OsiColCut.hpp.

bool OsiColCut::consistent | ( |  | ) | const
| inline virtual

Returns true if the cut is consistent with respect to itself.

This checks to ensure that:

- The bound vectors do not have duplicate indices,
- The bound vectors indices are >=0

Implements OsiCut.

Definition at line 218 of file OsiColCut.hpp.

bool OsiColCut::consistent | ( | const OsiSolverInterface & | im | ) | const
| inline virtual

    Returns true if cut is consistent with respect to the solver

interface's model.

This checks to ensure that the lower & upperbound packed vectors:

- do not have an index >= the number of column is the model.

Implements OsiCut.

Definition at line 233 of file OsiColCut.hpp.

bool OsiColCut::infeasible | ( | const OsiSolverInterface & | im | ) | const
| inline virtual

    Returns true if the cut is infeasible with respect to its bounds and the

column bounds in the solver interface's models.

This checks whether:

- the maximum of the new and existing lower bounds is strictly greater than the minimum of the new and existing upper bounds.

Implements OsiCut.

Definition at line 285 of file OsiColCut.hpp.

virtual double OsiColCut::violated | ( | const double * | solution | ) | const
| virtual

Returns infeasibility of the cut with respect to solution passed in i.e.

is positive if cuts off that solution. solution is getNumCols() long..

Implements OsiCut.

OsiColCut& OsiColCut::operator= | ( | const OsiColCut & | rhs | ) |

Assignment operator.

virtual OsiColCut* OsiColCut::clone | ( |  | ) | const
| virtual

Clone.

virtual void OsiColCut::print | ( |  | ) | const
| virtual

Print cuts in collection.

Reimplemented from OsiCut.

## Friends And Related Function Documentation

void OsiColCutUnitTest | ( | const OsiSolverInterface * | baseSiP,
|  | const std::string & | mpsDir
| ) |  |
| friend

A function that tests the methods in the OsiColCut class.
