Interface Optimizer

All Known Implementing Classes:

AbstractOptimizer, DifferentialEvolution, EvolutionaryAlgorithm, MOPSO, RandomSearch, SimulatedAnnealing

public interface Optimizer

This Optimizer interface has to be implemented by all population-based optimizers.

Method Summary

Modifier and Type	Method	Description
void	addOptimizerIterationListener(OptimizerIterationListener listener)	Adds an OptimizerIterationListener to this optimizer.
void	addOptimizerStateListener(OptimizerStateListener listener)	Adds an OptimizerStateListener to this optimizer.
int	getIteration()	Return the current iteration.
boolean	isRunning()	Returns true if the Optimizer is running.
void	optimize()	Starts the optimization process.
void	removeOptimizerIterationListener(OptimizerIterationListener listener)	Removes an OptimizerIterationListener from this optimizer.
void	removeOptimizerStateListener(OptimizerStateListener listener)	Removes an OptimizerStateListener from this optimizer.
void	startOptimization()	This method is called once the optimization process has started.
void	stopOptimization()	This method is called once the optimization process has stopped.
