Hi all, I'm new to ECJ and try to use GA's for parameter optimization. I have already extended ECJ but now run into a problem. Is there any possibility to create a type mixed Individual. It want to have a genome of type [float/int/boolean] (The types and length vary for each run, so I thought of a generic solution). I know that there is this GeneVectorIndividual, which I could extend as well as the VectorGene, but I think, it is not very comfortable to use this as I only use standard ECJ vector types. Is there any other way to solve this problem? Thank you in advance for your help!
