Description (last modified by gkronber)
User programmable functions for GP would increase flexibility of GP infrastructure. Because of performance considerations the evaluation for all commonly used functions for symbolic-regression and classification is hard-coded now. To increase the flexibility of evaluation (programmable-functions and newly defined functions in external plugins) it is necessary to extend the evaluator to delegate evaluation of unknown functions to a different evaluator. This should be rather easy since functions already define their own evaluator.

As suggested on the mailing list this feature should be implemented either in 3.3.7 or 3.3.8. As it is difficult to define custom functions in the current system.
