All Implemented Interfaces:

Serializable, Cloneable

public class EsOptimizerConfiguration
extends EaOptimizerConfigurationBase<EsIndividual>

A configuration for evolution strategies. The individuals' type of evolution strategies is always EsIndividual.

Additionally to the components in EaOptimizerConfigurationBase it contains:

• The number of offsprings that will be created per parent.

For an E(μ+/,λ)-evolution strategy these configuration has the following corresponding parameters:

• μ: the number of parents.
• + or ,: the preserveParents flag to indicate that parents should be preserved (plus-selection) or discarded (comma-selection).
• λ: the number of offspring created per parent.

Constructor Detail

EsOptimizerConfiguration

public EsOptimizerConfiguration()

Method Detail

clone

public EsOptimizerConfiguration clone()

Description copied from class: OptimizerConfiguration

Returns a shallow copy of this configuration. This will not clone the configuration's components.

Subclasses should override this method to cast the result to themself.

Overrides:

clone in class OptimizerConfiguration<EsIndividual>

Returns:

the shallow copy of this configuration

getOffspring

public final int getOffspring()

Returns:

the number of offspring

See Also:

setOffspring(int)

setOffspring

public final void setOffspring(int offspring)

Sets the number of offspring for the evolution strategy.

For an E(μ+/,λ)-evolution strategy, this sets the λ.

Parameters:

offspring - the number of offspring

Throws:

IllegalArgumentException - if offspring is zero or negative

hashCode

public int hashCode()

Overrides:

hashCode in class EaOptimizerConfigurationBase<EsIndividual>

equals

public boolean equals(Object obj)

Overrides:

equals in class EaOptimizerConfigurationBase<EsIndividual>

toString

public String toString()

Overrides:

toString in class Object
