• ProtoBuff QualityMessages
  • Changed the QualityMessage to be able to be used for single- and multi-objective problems.
  • The new SingleObjectiveQualityMessage and MultiObjectiveQualityMessage now "inherits" from QualityMessages to be able to be used in a polymorph manner.
  • This is done via protobuf's nested extensions (see ​http://www.indelible.org/ink/protobuf-polymorphism/).
• EvaluationCache
  • The EvaluationCache now now stores the QualityMessage instead of a single double. This way the cache can be used for single- and multi-objective problems and additionally opens the possibility to extend the quality message with any data. (previously extended data was lost when the cache was persisted and loaded again)
  • When deserializing an older version of the cache a new single objective quality message is created from the double value. This way, no compatibility is broken and version must not be incremented.
• Adapted the ExternalEvaluationProblem to the changes of the EvaluationCache and the QualityMessage.
• Added a MultiObjectiveExternalEvaluationProblem on basis of the ExternalEvaluationProblem and added a IExternalEvaluationProblem interface.
