The LBestTopology.iterator() method is not implemented, meaning the functionality is inherited from GBestTopology which returns a GBestNeighbourhoodIterator instead of an LBestNeighbourhoodIterator.

I used the standard xml/ga.xml file in the git repository to get the attached results.

The ec.EC algorithm configured with GeneticAlgorithmIterationStrategy is maximising problem that should be minimised.

Someone commented out the FitnessCalculator in the clustering.KMeans class, because FitnessCalculator now requires an Entity and KMeans only has a Vector. I don't recall when this change in FitnessCalculator was made. The Git logs don't contain the change.
KMeans is not a population based algorithm and therefore an Entity would not make sense. Is there another type of FitnessCalculator that...

Sorry, I clearly used the wrong terms. What I meant was:
dividing all elements of a vector by a scalar and then taking the norm of the
vector (which is a scalar)
...is the same as...
taking the norm of the vector (which is a scalar) and dividing it by the scalar.

2. A small change will allow the BoundedPositionUpdateStrategy to wrap/decorate any other PositionUpdateStrategy.
3. There are many other PositionUpdateStrategies (not just Random) that can only be achieved as pre-updates. Post boundary constraints will not be possible, since the Particle's position has already been updated and there is no way of knowing where it was at the previous step.

Some clarification:
The pso.iterationstrategies.BoundaryConstraint interface can be used for any Entity and not just a Particle. It should therefore be moved to a more generic package.
The pso.positionupdatestrategies.boundaryconstraintstrategies.BoundaryConstraintStrategy interface is used during the position update phase of Particles. It is therefore PSO specific, since other Entities do...

In revision 751 I also introduced the DataSetManager Singleton class. This class is responsible for parsing/initialising/constructing DataSets and DataSetBuilders only once.
A DataSet or DataSetBuilder can now be shared between all Threads of all Simulations. It works nicely, because they are read-only structures once they have been initialised.
Basically, a DataSetBuilder makes use of...

When I made the changes discussed in Request IDs 1969406 and 1969412, I also introduced the ClusteringUtils class.
This class now handles the formation/creation/arrangement of clusters. This simplified the AssociatedPairDataSetBuilder class to such a degree that it only deals with dataset stuff now, which is its actual purpose.
The AssociatedPairDataSetBuilder does not know about clusters...
