- Enclosing class:
- LinearSolver
static final class LinearSolver.NewIntegration extends ExpressionsBasedModel.Integration<SimplexSolver>
An integration to a new/alternative/experimental LP-solver. That solver is intended to replace the current solver, but is not yet ready to do that. You're welcome to try it - just add this integration by callingExpressionsBasedModel.addIntegration(ExpressionsBasedModel.Integration)

Method Detail
-
build
public SimplexSolver 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 ofOptimisation.Integration.toSolverState(Optimisation.Result, Optimisation.Model)
.- Specified by:
toModelState
in interfaceOptimisation.Integration<ExpressionsBasedModel,SimplexSolver>
- Overrides:
toModelState
in classExpressionsBasedModel.Integration<SimplexSolver>

- Overrides:

-
getIndexInSolver
protected int getIndexInSolver(ExpressionsBasedModel model, Variable variable)
- Overrides:
getIndexInSolver
in classExpressionsBasedModel.Integration<SimplexSolver>
- Returns:
- The index with which one can reference parameters related to this variable in the solver.
