- 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 calling
ExpressionsBasedModel.addIntegration(ExpressionsBasedModel.Integration)

Description copied from interface:Optimisation.Integration
An integration must be able to instantiate a solver that can handle (any) model instance. -
isCapable
- 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)
