Method Detail

make

public static MathProgSysModel make(File file)

dispose

public void dispose()

Description copied from interface: Optimisation.Model

Cleanup when a model instance is no longer needed. The default implementation does nothing,

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

getExpressionsBasedModel

public ExpressionsBasedModel getExpressionsBasedModel()

Returns:

The delegate ExpressionsBasedModel

getName

public String getName()

hashCode

public int hashCode()

Overrides:

hashCode in class Object

maximise

public Optimisation.Result maximise()

Will disregard the OBJSENSE and maximise.

See Also:

Optimisation.Model.maximise()

minimise

public Optimisation.Result minimise()

Will disregard the OBJSENSE and minimise.

See Also:

Optimisation.Model.minimise()

solve

public Optimisation.Result solve()

If the OBJSENSE was specified in the file it is used otherwise the default is to minimise.

The solution (variable values) are in the order the columns were defined in the MPS-file.

toString

public String toString()

Overrides:

toString in class Object

validate

public boolean validate()

Returns:

true If eveything is ok. false The model is structurally ok, but the "value" breaks constraints - the solution is infeasible.

validate

public boolean validate(Access1D<BigDecimal> solution,
                        NumberContext context)

See Also:

ExpressionsBasedModel.validate(org.ojalgo.access.Access1D, org.ojalgo.type.context.NumberContext)

isMaximisation

public final boolean isMaximisation()

isMinimisation

public final boolean isMinimisation()

setMaximisation

public final void setMaximisation()

setMinimisation

public final void setMinimisation()

setMaximisation

protected final void setMaximisation(boolean maximisation)

setMinimisation

protected final void setMinimisation(boolean minimisation)
