@FunctionalInterface
public interface MisplacedVMsEstimator

An interface to specify an object that can estimated a supposed set of misplaced VMs in a model.

This information will be used by the ChocoScheduler to restrict the amount of VMs to consider in the scheduler to a minimum.

The set of mis-placed VMs is not necessarily optimal but it must be good enough to be able to compute a solution by only managing these VMs.
