Method Detail

runOptimization

public void runOptimization(ProblemXMLData problemData,
                   ComponentXMLData representationData,
                   ComponentXMLData rankingData,
                   java.util.Hashtable<java.lang.String,XMLFieldEntry> properties)

Specified by:

runOptimization in class AbstractMethod

saveResults

public org.dom4j.Element saveResults(int generation)

Saves all population data to a new XML element and returns it.

loadFromXML

public java.util.ArrayList<java.util.ArrayList<AbstractRepresentation>> loadFromXML(org.dom4j.Document doc)

Description copied from class: AbstractMethod

Returns a 2D array of representations from the given XML result file. This is mostly used for visual representations.

If the loading takes considerable amount of time it is advised to provide visual feedback to the user. This can be done by calling the FrevoMain.setLoadingProgress(float) method.

Specified by:

loadFromXML in class AbstractMethod

Parameters:

doc - The source Document to be used for loading the representations.

Returns:

A 2D array of AbstractRepresentations loaded from the source document.
