  UnionMoveSelector<Solution_> | A `CompositeMoveSelector` that unions 2 or more `MoveSelector`s.
  UnionMoveSelectorConfig |
  UnionMoveSelectorFactory<Solution_> |
  UpcomingSelectionIterator<S> | IMPORTANT: The constructor of any subclass of this abstract class, should never call any of its child `Selector`'s `Iterator.hasNext()` or `Iterator.next()` methods, because that can cause descendant `Selector`s to be selected too early (which breaks `MimicReplayingEntitySelector`).

  WeightedScoreImpacter |
  WeightFactorySelectionSorter<Solution_,​T> | Sorts a selection `List` based on a `SelectionSorterWeightFactory`.
  WorstScoreSolverRankingComparator | This ranking `Comparator` orders a `SolverBenchmarkResult` by its worst `Score`.
  XsdAggregator | This class merges solver.xsd and benchmark.xsd into a single XML Schema file that contains both Solver and Benchmark XML types under a single namespace of the benchmark.xsd.
  XStreamSolutionFileIO<Solution_> | Security warning: only use this class with XML files from a trusted source, because `XStream` is configured to allow all permissions, which can be exploited if the XML comes from an untrusted source.
