Package org.ojalgo.optimisation.service

Class OptimisationService

java.lang.Object

org.ojalgo.optimisation.service.OptimisationService

public final class OptimisationService
extends java.lang.Object

Basic usage:

1. Put optimisation problems on the solve queue by calling putOnQueue(Sense, byte[], FileFormat)
2. Check the status of the optimisation by calling getStatus(String) – is it OptimisationService.Status.DONE or still OptimisationService.Status.PENDING?
3. Get the result of the optimisation by calling getResult(String) – when OptimisationService.Status.DONE
