 v3 [[http://dev.heuristiclab.com/trac/hl/core/wiki/UsersSamples#GeneticProgramming | Samples for Genetic Programming]] HeuristicLab supports tree-based (Koza-style) genetic programming. This classical form of genetic programming uses a tree-based representation of solution candidates. The data types and operators to work with tree-bsaed solution candidates are implemented in the plugin HeuristicLab.Encodings.SymbolicExpressionTree.
