6.9.1 Detailed Description

template<class BaseType, class CoType> class ABA_LPSOLUTION< BaseType, CoType >

template class implements an LP solution. This class is necessary when using the class ABA_SEPARATOR for separation.

Parameters:

ABA_MASTER: *master_ A pointer to the corresponding master of the optimization.
int: nVarCon_ The number of variables/constraints.
int: idSub_ The Id of the subproblem in which the LP solution was generated.
int: idLp_ The Id of the LP in which the LP solution was generated.
ABA_ARRAY<double>: * zVal_ The primal/dual variables of the LP solution.
ABA_ACTIVE<BaseType,CoType>: *active_ The active variables/constraints.

6.9.2 Constructor & Destructor Documentation

6.9.2.1 template<class BaseType, class CoType> ABA_LPSOLUTION< BaseType, CoType >::ABA_LPSOLUTION (ABA_SUB * sub, bool primalVariables, ABA_ACTIVE< BaseType, CoType > * active)

The constructor.

Parameters:

sub: A pointer to the subproblem in which the LP solution is generated.
primalVariables: True if ABA_LPSOLUTION contains the primal variables. In this case BaseType must be ABA_VARIABLE. If primaVariables is false, then BaseType must be ABA_CONSTRAINT.
active: The active variables/constraints that are associated with the LP solution. The default argument is 0. Then the set of active variables/constraints is not stored, but is assumed to be fixed and known.

6.9.2.2 template<class BaseType, class CoType> ABA_LPSOLUTION< BaseType, CoType >::ABA_LPSOLUTION (ABA_MASTER * master)

The constructor.

Parameters:

master: A pointer to ABA_MASTER.

6.9.2.3 template<class BaseType, class CoType> ABA_LPSOLUTION< BaseType, CoType >::ABA_LPSOLUTION (const ABA_LPSOLUTION< BaseType, CoType > & rhs)

The copy constructor.

Parameters:

rhs: The LP solution that is copied.

6.9.2.4 template<class BaseType, class CoType> ABA_LPSOLUTION< BaseType, CoType >::~ABA_LPSOLUTION ()

The destructor.

6.9.3.2 template<class BaseType, class CoType> double*ABA_LPSOLUTION< BaseType, CoType >::zVal ()

Returns:: The primal/dual variables of the LP solution.

6.9.3.3 template<class BaseType, class CoType> ABA_ACTIVE<BaseType, CoType>*ABA_LPSOLUTION< BaseType, CoType >::active ()

Returns:: The active variables/constraints.

6.9.3.4 template<class BaseType, class CoType> int ABA_LPSOLUTION< BaseType, CoType >::idSub () const

Returns:: The Id of the subproblem in which the LP solution was generated.

6.9.3.5 template<class BaseType, class CoType> int ABA_LPSOLUTION< BaseType, CoType >::idLp () const

Returns:: The Id of the LP in which the LP solution was generated.
