Constructor Detail

GaussianMutationOperator

public GaussianMutationOperator()
                         throws InvalidConfigurationException

Constructs a GaussianMutationOperator with a default deviation of 0.05. Attention: The configuration used is the one set with the static method Genotype.setConfiguration.

Throws:

InvalidConfigurationException

Since:

2.0

GaussianMutationOperator

public GaussianMutationOperator(Configuration a_config)
                         throws InvalidConfigurationException

Constructs a GaussianMutationOperator with a default deviation of 0.05.

Parameters:

a_config - the configuration to use

Throws:

InvalidConfigurationException

Since:

3.0

GaussianMutationOperator

public GaussianMutationOperator(Configuration a_configuration,
                                double a_deviation)
                         throws InvalidConfigurationException

Constructs a GaussianMutationOperator with the given deviation.

Parameters:

a_configuration - the configuration to use

a_deviation - sic

Throws:

InvalidConfigurationException

Since:

3.0 (since 2.0 without a_configuration)

Method Detail

operate

public void operate(Population a_population,
                    java.util.List a_candidateChromosomes)

Executes the operation.

Parameters:

a_population - containing chromosomes to be mutated

a_candidateChromosomes - resulting chromosomes

Since:

2.0

compareTo

public int compareTo(java.lang.Object a_other)

Compares the given GeneticOperator to this GeneticOperator.

Parameters:

a_other - the instance against which to compare this instance

Returns:

a negative number if this instance is "less than" the given instance, zero if they are equal to each other, and a positive number if this is "greater than" the given instance

Since:

2.6

getDeviation

public double getDeviation()

Returns:

the deviation set

Since:

3.1
