Constructor Detail

DBEA

public DBEA(Problem problem,
            Initialization initialization,
            Variation variation,
            int divisionsOuter,
            int divisionsInner)
Method Detail

initialize

protected void initialize()
Description copied from class: AbstractAlgorithm
Performs any initialization that is required by this algorithm. This method is called automatically by the first invocation of AbstractAlgorithm.step(), but may also be called manually prior to any invocations of step. Implementations should always invoke super.initialize() to ensure the hierarchy is initialized correctly.

Overrides:
initialize in class AbstractEvolutionaryAlgorithm

iterate

protected void iterate()
Description copied from class: AbstractAlgorithm
Performs one iteration of the algorithm. This method should be overridden by implementations to perform each logical iteration of the algorithm.

Specified by:
iterate in class AbstractAlgorithm

getResult

public NondominatedPopulation getResult()
Description copied from interface: Algorithm
Returns the current best-known result.

Specified by:
getResult in interface Algorithm
Overrides:
getResult in class AbstractEvolutionaryAlgorithm
Returns:
the current best-known result
