 Title: Grammatical Evolution for R
 Version: 2.1-3

 Author: Farzad Noorian, Anthony Mihirana de Silva

 Description: A native R implementation of grammatical evolution (GE). GE facilitates the discovery of programs that can achieve a desired goal. This is done by performing an evolutionary optimisation over a population of R expressions generated via a user-defined context-free grammar (CFG) and cost function.
