Interface Optimization

All Known Implementing Classes:

ESOptimization, ESParameterOptimization, EvoOptimization, PSOOptimization, PSOSVMOptimization, PSOWeighting.PSOWeightingOptimization

public interface Optimization

General interface for all optimization methods. The method optimize() should be invoked to start the optimization process. The optimal result can be queried by the method getBestValuesEver(). The other methods of this interface can be used to support logging or plotting.

Method Summary

double	getBestFitnessEver() Returns the best fitness ever.
double	getBestFitnessInGeneration() Returns the best fitness in the current generation.
PerformanceVector	getBestPerformanceEver() Returns the best performance vector ever.
double[]	getBestValuesEver() Returns the best values ever.
int	getGeneration() Returns the current generation.
void	optimize() Should be invoked to start optimization.

Method Detail

optimize

void optimize()
              throws OperatorException

Should be invoked to start optimization. Since the optimization can use other (inner) operators to support fitness evaluation this method is allowed to throw OperatorExceptions.

Throws:

OperatorException

getGeneration

int getGeneration()

Returns the current generation.

getBestFitnessInGeneration

double getBestFitnessInGeneration()

Returns the best fitness in the current generation.

getBestFitnessEver

double getBestFitnessEver()

Returns the best fitness ever.

getBestPerformanceEver

PerformanceVector getBestPerformanceEver()

Returns the best performance vector ever.

getBestValuesEver

double[] getBestValuesEver()

Returns the best values ever. Use this method after optimization to get the best result.
