ScoreDefinitionScore is the Score of which there is no better in any problem instance.
This doesn't mean that the current problem instance, or any problem instance for that matter,
could ever attain that Score.
For example, most cases have a perfect maximum Score of zero, as most use cases only have negative
constraints.

public HardSoftDoubleScore getPerfectMinimumScore()
ScoreDefinitionScore is the Score of which there is no worse in any problem instance.
This doesn't mean that the current problem instance, or any problem instance for that matter,
could ever attain such a bad Score.
For example, most cases have a perfect minimum Score of negative infinity.
