Method Detail

copy

public final QuadraticExpressionsModel copy()

Specified by:

copy in class ExpressionsBasedModel<QuadraticExpressionsModel>

getDefaultSolver

public OptimisationSolver getDefaultSolver()

Description copied from interface: OptimisationModel

No need to implement an OptimisationModel if there is not at least one matching OptimisationSolver.

Specified by:

getDefaultSolver in interface OptimisationModel

Specified by:

getDefaultSolver in class ExpressionsBasedModel<QuadraticExpressionsModel>

validateComposition

public boolean validateComposition()
                            throws ModelValidationException

Description copied from interface: OptimisationModel

OptimisationModel is meant to be implemented in parallel with OptimisationSolver. This method indicates if the model is built in a way the solver can handle or not.

Specified by:

validateComposition in interface OptimisationModel

Overrides:

validateComposition in class ExpressionsBasedModel<QuadraticExpressionsModel>

Throws:

ModelValidationException

isMaximisation

public final boolean isMaximisation()

isMinimisation

public final boolean isMinimisation()

setMaximisation

public final void setMaximisation(boolean aFlag)

setMinimisation

public final void setMinimisation(boolean aFlag)
