Package org.uma.jmetal.component.algorithm

Class EvolutionaryAlgorithm<S extends Solution<?>>

java.lang.Object

org.uma.jmetal.component.algorithm.EvolutionaryAlgorithm<S>

Type Parameters:

S - Generic type representing the encoding of the solutions

All Implemented Interfaces:

Serializable, Runnable, Algorithm<List<S>>, ObservableEntity<Map<String,Object>>

public class EvolutionaryAlgorithm<S extends Solution<?>>
extends Object
implements Algorithm<List<S>>, ObservableEntity<Map<String,Object>>

Template for evolutionary algorithms. Its mains features are: - The steps of the algorithm are carried out by objects (components) - The algorithms are ObservableEntity, which can be observed by Observer objects. - The observable element is a map of pairs (String, Object), which is initialized and updated by the initProgress() and updateProgress() methods.
