ModelIntegration

public ModelIntegration()

Method Details

build

public ConvexSolver build(ExpressionsBasedModel model)

Description copied from interface: Optimisation.Integration

An integration must be able to instantiate a solver that can handle (any) model instance.

isCapable

public boolean isCapable(ExpressionsBasedModel model)

Returns:

true if this solver (integration) can handle the input 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,ConvexSolver>

Overrides:

toModelState in class ExpressionsBasedModel.Integration<ConvexSolver>

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).
