  Description copied from interface: `ScoreCalculator`
  Calculates the score: the solution (encountered at a step) with the highest score will be seen as the the best solution. The step score calculation should be kept stable over all steps. When the solution is modified during a Move, the WorkingMemory's FactHandles should have been correctly notified. Before the score is calculated, all rules are fired, which should trigger an update of this instance.

  Returns:
    never null, the score of the solution
