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

inlinevirtual

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

inlinevirtual

not equal

Definition at line 209 of file OsiColCut.hpp.

bool OsiColCut::consistent ( ) const

inlinevirtual

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

inlinevirtual

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

inlinevirtual

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.
