Message:

Added interface IModel and a standard implementation and changed SVM models to include the range transform in the model. #650 (IAlgorithm and derived interfaces should provide properties to retrieve results)

Location:

trunk/sources/HeuristicLab.GP.StructureIdentification/3.3

Files:

• AlgorithmBase.cs (modified) (2 diffs)
• StandardGP.cs (modified) (1 diff)
