GAFitnessEvaluator

public GAFitnessEvaluator(TransformNode inputNode,
                          String[] outputTypes,
                          TransformGraph graph)

Method Detail

evalObjFun

public double evalObjFun(Vector data)

Description copied from interface: GAFramework.Evaluator

Evaluate the objective function given the chromosome or the phenotype of some individual.

Specified by:

evalObjFun in interface GAFramework.Evaluator

Parameters:

data - is the vector with the genetic data (chromosome) or the phenotype of some individual. If Individual.GENOT has been passed to the constructor of GenerationProcess, then data is interpreted as the chromosome. If Individual.PHENOT was used instead, then the argument data is interpreted as the phenotype.

Returns:

a double value with the objective function evaluation.

evalFitness

public double evalFitness(Vector data)

Description copied from interface: GAFramework.Evaluator

Evaluate the fitness of some individual given its genetic data (chromosome) or its phenotype. If this signature is used for the fitness evaluation implementation, according to the problem to be solved, then the another version must be a "do nothing" method.

Specified by:

evalFitness in interface GAFramework.Evaluator

Parameters:

data - is the chromosome or the phenotype of some individual.If Individual.GENOT has been passed to the constructor of GenerationProcess, then data is interpreted as the chromosome. If Individual.PHENOT was used instead, then the argument data is interpreted as the phenotype.

Returns:

a double with the individual fitness.

evalFitness

public double evalFitness(double objfun)

Description copied from interface: GAFramework.Evaluator

Evaluate the fitness of some individual given its objective function value. If this signature is used for the fitness evaluation implementation, according to the problem to be solved, then the another version must be a "do nothing" method.

Specified by:

evalFitness in interface GAFramework.Evaluator

Parameters:

objfun - is the value of objective function obtained by some individual.

Returns:

a double with the individual fitness.
