Method Detail

get

public static Archive get()

Static entrypoint to get to the Archive. This method is usefull especially in situations where you need to get to the archive from different locations such as a GuideSelectionStrategy, or the ArchivingIterationStep at the end of a multi-objective algorithm.

Returns:

The currently active archive for a multi-objective algortihm.

set

public static void set(Archive archive)

Set the archive to be used by a multi-objective optimisation algorithm.

Parameters:

archive - A concrete archive implementation to be used as the active archive.

dominates

public abstract Collection<OptimisationSolution> dominates(OptimisationSolution candidateSolution)

Checks the entire archive and accumulates the solutions that dominates candidateSolution.

Parameters:

candidateSolution - The solution to compare against all of the solutions in the archive.

Returns:

The collection of solutions that dominates candidateSolution.

isDominatedBy

public abstract Collection<OptimisationSolution> isDominatedBy(OptimisationSolution candidateSolution)

Checks the archive and accumulates all solutions that is dominated by candidateSolution.

Parameters:

candidateSolution - The solution to compare against all of the solutions in the archive.

Returns:

The collection of solutions dominated by the candidateSolution.
