  • created extension method GetObjectGraphObjects for objects
  • created IStatefulItem interface, which means an object has a state which can be initialized and cleared
  • after an algorithm stopped, all objects of the algorithm-objectgraph with the type IStatefulItem are cleared
  • on prepare, all IStatefulItem objects are initialized
