Class ZeroEvalScoreFunction

java.lang.Object

org.encog.ml.prg.train.ZeroEvalScoreFunction

All Implemented Interfaces:

java.io.Serializable, CalculateScore

public class ZeroEvalScoreFunction
extends java.lang.Object
implements CalculateScore, java.io.Serializable

This is a very simple evaluation function that simply passes in all zeros for the input arguments. Make sure that the genome you are testing supports floating point numbers for inputs. This evaluation function is useful to test to very quickly verify that a genome is valid and does not generate any obvious division by zero issues. This allows a population generator to quickly eliminate some invalid genomes.
