Method Details

extractSolverState

public final Optimisation.Result extractSolverState(ExpressionsBasedModel model)

Description copied from interface: Optimisation.Integration

Extract state from the model and convert it to solver state.

Specified by:

extractSolverState in interface Optimisation.Integration<ExpressionsBasedModel,S extends Optimisation.Solver>

See Also:

• Optimisation.Integration.extractSolverState(Optimisation.Model)

toModelState

public Optimisation.Result toModelState(Optimisation.Result solverState,
 ExpressionsBasedModel model)

Description copied from interface: Optimisation.Integration

Convert solver state to model state. Transforming the solution (set of variable values) is the main concern. Adjusting the objective function value (if needed) is best handled elsewhere, and is not required here.

The required behaviour here depends on how Optimisation.Integration.build(Optimisation.Model) is implemented, and is the reverse mapping of Optimisation.Integration.toSolverState(Optimisation.Result, Optimisation.Model).

Specified by:

toModelState in interface Optimisation.Integration<ExpressionsBasedModel,S extends Optimisation.Solver>

toSolverState

public Optimisation.Result toSolverState(Optimisation.Result modelState,
 ExpressionsBasedModel model)

Description copied from interface: Optimisation.Integration

Convert model state to solver state. Transforming the solution (set of variable values) is the main concern. Adjusting the objective function value (if needed) is best handled elsewhere, and is not required here.

The required behaviour here depends on how Optimisation.Integration.build(Optimisation.Model) is implemented, and is the reverse mapping of Optimisation.Integration.toModelState(Result, Optimisation.Model).

Specified by:

toSolverState in interface Optimisation.Integration<ExpressionsBasedModel,S extends Optimisation.Solver>

withCapabilityPredicate

public final ExpressionsBasedModel.Integration<S> withCapabilityPredicate(Predicate<ExpressionsBasedModel> capabilityPredicate)

Use this to limit the cases where this Optimisation.Integration would be used.

Returns a new Integration instance where the supplied Predicate needs to test true in addition to the underlying Optimisation.Integration.isCapable(Optimisation.Model).

withOptionsModifier

public final ExpressionsBasedModel.Integration<S> withOptionsModifier(Consumer<Optimisation.Options> optionsModifier)

Intercept and modify the Optimisation.Options instance before building the solver.

getIndexInSolver

protected int getIndexInSolver(ExpressionsBasedModel model,
 Variable variable)

Returns:

The index with which one can reference parameters related to this variable in the solver.

isSwitch

protected final boolean isSwitch(ExpressionsBasedModel model,
 ExpressionsBasedModel.IntegrationProperty property)

newValidator

protected final ExpressionsBasedModel.Validator newValidator(ExpressionsBasedModel model)

setSwitch

protected final void setSwitch(ExpressionsBasedModel model,
 ExpressionsBasedModel.IntegrationProperty property,
 boolean value)
