public interface NeedsRandomGenerator
extends Serializable

Implementing this interfaces enables injection of seeded RandomGenerator -instances.

In distributed environments it's important to have the random-generators seeded correctly (differently) to avoid correlations between the generated random numbers on different machines. The Framework injects correctly seeded RandomGenerator objects in all components of an OptimizerConfiguration.
