Method Detail

getStarPool

public SubPopulation getStarPool()

Returns star pool.

Returns:

starPool a population with interesting solutions

See Also:

setStarPool(boolean)

setStarPool

public void setStarPool(boolean peaks)
                 throws JEvolutionException

Creates star pool with specific modes. The modes indicate which solutions should be stored. Only supported mode now is `peaks', where each newly found best solution is added to the pool.

Parameters:

peaks - store peak Individuals (if false, no pool)

Throws:

JEvolutionException

getReportLevel

public int getReportLevel()

Access report level.

Returns:

reportLevel The amount of information reported.

setReportLevel

public void setReportLevel(int reportLevel)
                    throws JEvolutionException

Change report level.

Parameters:

reportLevel - The amount of information reported.

Throws:

JEvolutionException - Invalid level.

isFitnessRepositoryUsed

public boolean isFitnessRepositoryUsed()

Access status of the use of fitness repository.

Returns:

useFitnessRepository It is used or it is not used.

useFitnessRepository

public void useFitnessRepository(boolean on)

Switch the use of fitness repository on/off. Create a Repository, if there is none.

Parameters:

on - Turns it on/off.

getIndividualsDone

public int getIndividualsDone()

Access the current number of fitness calculations performed.

Returns:

individualsDone The number of individuals evaluated.

getBestIndividual

public Individual getBestIndividual()

Gives the best Individual of the last run.

Returns:

bestIndividual Individual with best fitness

setPrintWriter

public void setPrintWriter(java.io.PrintWriter printWriter)

Define the output sink for reports. You may set it to 'null' to supress any output, but setting the report level to QUIET is the preferred method. For safe operation be sure to set the auto-flush flag of the PrintWriter, as long evolution runs (with detailed output, e.g., VERBOSE) may cause a large buffer space allocated by the PrintWriter.

Parameters:

printWriter - prints results to attached device
