Method Detail

evaluate

public void evaluate(Population a_subject)

Determine the fitness of the given Chromosome instance. The higher the returned value, the fitter the instance. This method should always return the same fitness value for two equivalent Chromosome instances.

Specified by:

evaluate in class BulkFitnessFunction

Parameters:

a_subject - the population of chromosomes to evaluate

Since:

2.6

getVector

public static java.util.Vector<java.lang.Double> getVector(IChromosome a_chrom)

Parameters:

a_chrom - the chromosome for which to obtain the result it represents

Returns:

vector of data for output

formula

public static double formula(int a_index,
                             double a_x)

clone

public java.lang.Object clone()

Description copied from class: BulkFitnessFunction

Override in your implementation if necessary.

Specified by:

clone in interface ICloneable

Overrides:

clone in class BulkFitnessFunction

Returns:

deep clone of the current instance
