Examples of PrgGrowGenerator

org.encog.ml.prg.generator.PrgGrowGenerator
The grow generator creates a random program by choosing a random node from both the "function and terminal" sets until the maximum depth is reached. Once the maximum depth is reached only nodes from terminal set are chosen. This algorithm was implemented as described in the following publication: Genetic programming: on the programming of computers by means of natural selection MIT Press Cambridge, MA, USA (c)1992 ISBN:0-262-11170-5
