public SMGraphAStarOneImpl()

Method Detail

getSystemName

public String getSystemName()

Description copied from interface: SimilarityMeasure

The system name can be used to distinguish the similarity measures. Each similarity measure that can be instantiated contains a static final field called NAME representing the system name, e.g., SMAggregateEuclidian.NAME

The system name must also be given during initialization, see SimilarityModel.createSimilarityMeasure(String, DataClass).

Specified by:

getSystemName in interface SimilarityMeasure

Returns:

The system name of the similarity measure. This is equal to SimilarityMeasure.NAME.

selectNextItem

protected NESTGraphItemObject selectNextItem(AStarCaseSolution toExpand)

Description copied from class: SMGraphAStarImpl

Retrieves the next item of the queryGraph based on the concrete AStar-implementation.

Specified by:

selectNextItem in class SMGraphAStarImpl

Parameters:

toExpand - The item which should be expanded.

Returns:

Selected item.

estimateSimilarity

protected double estimateSimilarity(AStarCaseSolution newSol,
                                    AStarGraphItemMapping newMap)

Description copied from class: SMGraphAStarImpl

Estimates the similarity for the remaining items of the queryGraph based on the concrete AStar-implementation.

Specified by:

estimateSimilarity in class SMGraphAStarImpl

Returns:
