Class CrossOverScheme
java.lang.Object
es.udc.gii.common.eaf.algorithm.operator.reproduction.mutation.de.crossover.CrossOverScheme
- All Implemented Interfaces:
- Configurable
- Direct Known Subclasses:
- BinCrossOverScheme, ExpCrossOverScheme
public abstract class CrossOverScheme
- extends java.lang.Object
- implements Configurable
In order to increase the diveristy of the population, the DE algorithm uses a crossover operator.
After the generation of the mutated individual, a crossover operator is execute to the mutated vector
and the target vector.
This operator is applied over these two vectors and it generates a new vector, the trial one.
This trial vector has some genes from the mutated vector and other from the target vector.
As this is an abstract class, it could not be instanciate, but when we use a subclass that inherit
from it, its xml configuration code should have at least a configuration for the CR parameter,
among other specific configuration parameters of the subclass. So the xml code should be like this:
<CrossOverScheme>
<Class>value</Class>
<CR>value</CR>
...
<CrossOverScheme>
where the tag lt;Class> indicates a subclass of this abstract class and
CR indicates the plugin used. If some of the parameters do not appear in the configuration, they are set
to their default values.
Default values:
- CR is set to Constant parameter with value 0.1
- Since:
- 1.0
