Method Detail

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(org.ojalgo.optimisation.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.

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.

Specified by:

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

isSolutionMapped

protected abstract boolean isSolutionMapped()

Returns:

true if the set of variables present in the solver is not precisely the same as in the model. If fixed variables are omitted or if variables are split into a positive and negative part, then this method must return true
