Does the new version supersede the previous version?: Yes
Nature of problem:
The technique of function estimation tries to discover from a series of input data a functional form that best describes them. This can be performed with the use of parametric models, whose parameters can adapt according to the input data.
Functional forms are being created by genetic programming which are approximations for the symbolic regression problem.
Reasons for new version:
The GDF package was extended in order to be more flexible and user customizable than the old package. The user can extend the package by defining his own error functions and he can extend the grammar of the package by adding new functions to the function repertoire. Also, the new version can perform function estimation of multi-output functions and it can be used for classification problems.
Summary of revisions:
The following features have been added to the package GDF:
A technical report describing the revisions, experiments and test runs is packaged with the source code.
Depending on the train data.
